What is the difference between density and viscosity?

Resistance measurement of fluid that is being deformed by shear stress or tensile stress is called viscosity. In simple words, we can say that the internal resistance of fluid is called viscosity. It is related to the thickness of the fluid.

Density is equal to mass per unit volume. We can say that density is just the weight of the fluid. The unit of density is Kgm-3.


The main difference between density and viscosity

Many people consider the density and viscosity the same terms but these are not the same and have a truly different concept.

  • The measurement of the molecular weight of a composition is called density. So it tells the weight of the fluid while the measurement of intermolecular force and molecule shape is called Viscosity. Through viscosity, we find the friction between 2 layers of any fluid.
  • With temperature, viscosity change rapidly while the density change gradually with temperature. Density and viscosity decrease with an increase in temperature and both have different physical phenomenon and these are depending on different aspects totally.


What is the difference between Listening and Hearing?

The act of perceiving sound and receiving sound waves through our ears is called Hearing. Act of hearing and understanding what we hear is called Listening. Hearing is the sense which happened all the time unless someone has a hearing problem.

For hearing, we use only our ears and for listening, we not only use our ear but sound goes to the brain to process the mean of sound. Listening used to build a better relationship with others but in case of hearing, we just receive sound through our ears only.

Listening is the communication technique through which we understand, interpret, and put the meaning of what we hear while hearing is just used to receive sound by our ear.


Comparison of hearing and listening

  • For both listening and hearing ears used.
  • Hearing is the receiving of sound waves through our ears, while listening is the receiving of sound waves through our ears and understand what we heard.
  • Hearing is the sense while listening is the choice for us that what we hear and analyze.
  • In hearing only ears used while in listening to other body parts also use.
  • In listening, we observe the behavior of others while in hearing we just receive waves of sound.
  • To build better relationship with other listening need while hearing not.


What is the difference between Village life and City life?

The way of living is different in villages and cities. You can easily found all the facilities in the city which you have not in village life. We found our inner peace in village life. There are arrays of trees, patches of green lands, ponds found in the village.

In cities, large numbers of people live whereas in the village the population is less. As compared to the city, the environment in the village is clean. There are less noise and fresh air in the village as compared to cities. People in the cities are busier as compare to the people of the village. There are large numbers of buildings and vehicles in the cities and cities offer better medical care as compare to the villages. Education facilities are better in the city as compare to the village.


Main differences between village and City

  • In the village, the main means of transport are the bullock cart, horse cart, and bicycles whereas the main means of transport in cities are bike, car, cab services, and metro railways.
  • Peoples of the village are no stranger to each other and they meet every day while life is busy in the city and people can meet with each other in events like parties, holidays, etc.
  • The environment of the city is polluted, noisy and crowded whereas the environment of the village is clean, not noisy, and not crowded.
  • In cities home, offices, and rooms are getting smaller day by day whereas in the village the home has large areas.
  • There are universities and colleges in the city for education but in the village, there are only government schools and college is not available in the village.
  • The scope of employment is more in the city because of the companies and industries whereas the peoples of the village do farming in the village mostly.

What is the difference between Since and For?

The main difference between since and for is that since is used with a particular point in time whereas for is used to specify the period of time.


For is used to talk about time amount or space. Time amount may be seconds, minute, hours, days, month and year. Time amount not need to be exact. To talk about vague time period for is used like for weekend, for years.

With a particular pint in time, since is used in English. Since use with present perfect and past perfect tenses. In many songs the word since use which you can hear on your mobile device or computer.

For use with a period of time while since used with a specific point in time. In similar verb tenses, for and since can be used. Here are examples:

I have been running for 7 hours.

I have been running for 5 pm.

We have studied here for 3 years.

We have studied here since 2017.


What is the difference between Perimeter and Area?

In geometry perimeter and Area are different terms. The area is the 2-dimensional region occupied by the close figure whereas perimeter total distance around the close figure is called a perimeter.

Area calculation needs the size of the calculation of carpet to cover the floor of the room. To surround the field or garden with a fence, we need to calculate the perimeter of the field or garden first then we can get the exact length of fence which we require to surround the field or garden. For different shapes, there are different formulas to calculate the area and perimeter.

To calculate the irregular shape we need to break the irregular shape into a common shape like square, rectangle, circle, and triangle. Then we can set formula for these common figures to calculate the area. In this way, we will be able to calculate the area of irregular figures.


Comparison between Perimeter and Area

  • Are calculate the space that occupies by the close figure whereas the perimeter calculates the distance around the close figure.
  • The area used to calculate 2-dimensional figure while perimeter used for the calculation of 1 dimension.
  • As the area is used to calculate 2 dimension due to which it has a square unit while the perimeter is used to measure 1 dimension due to which it has a linear unit.


What is the difference between Culture and Tradition?

There is the main difference between culture and tradition. Culture is the social behaviour or idea of the particular generation whereas tradition is the transferring of particular customs and belief from 1 generation to the next generation.


Culture VS Tradition

Culture is the fashion of the specific group of the people over a long time whereas tradition is created by one. Some families or individuals perform the tradition and it is unique whereas culture present among the large group of people. Entire Knowledge of human behaviour including clothing, language, art, belief and ritual is called culture whereas performing the culture in a specific way by specific families or individual generation by generation is called tradition.

Comparison between Culture and Tradition

  • Culture present in a particular social group whereas tradition present in an individual or particular families.
  • Culture perform by the large area of the social group whereas tradition is the part of the culture that is performed by some families.
  • A culture created by particular social group over the large time whereas tradition created by families or individuals.
  • Culture not change from generation to generation whereas tradition change and evolve with time and it is started to die out in the modern era.


What is the difference between Veterans Day and Memorial Day?

The main difference between Memorial Day and Veterans Day is that Veterans Day celebrated to honours the living soldiers who died our country Whereas Memorial day is the day on which we honour the soldiers of our country who died during the battle for the country.


On Veterans Day, all the peoples posting photos with brothers and friends in uniform or selfie with your bestie before he died. There are many businesses that offer a discount. People call their favourite vets to thanks their service for the country. People attend the parade and celebrate Veterans Day.

Memorial Day is about to honours the died soldiers. People attend the cemeteries and decorate the graves of soldiers on Memorial Day. Peoples talk their kids about sacrifice and tells the purpose of 3 day weekend of Memorial. On Memorial Day at 3:00 pm, peoples observe the National Moment of Remembrance with a minute of silence.


What is the Difference between Resistor, Capacitor, and Inductor?

A resistor is used to resist the current flow. The mean of resistance is a hurdle, refuse, and oppose. Resistor consumes electrical energy. Resistance occurs because of the collision of electrons with each other in the conductor due to which conductor heats up.

Capacitor and inductor both use to store energy but the process of storing energy in both is different. The capacitor used to store energy in the form of an electrostatic field whereas Inductor used to store energy in the form of the electromagnetic field. As compared to the inductor, the capacitor stores more energy.

An example of Inductor is a bulb that takes less time to on and off. The capacitor is like the tank which takes time to fill and drain it out.

From the above definition of resistor, capacitor, and inductor we conclude that the resistor is the energy-consuming device whereas capacitor and inductor is the energy storing device.


What is the difference between Evaporation and Vaporization?

Many people consider vaporization and evaporation the same term but in reality, both are different terms. One common point between these 2 terms is that in both terms liquid change in the gaseous state.


Evaporation is the process in which water changes in the gaseous state due to the rise in temperature or pressure.


The vaporization process is the process in which liquid changes into the gaseous state when the temperature reaches above the boiling point.

At any time when the molecules of water absorb energy from surrounding and change in the gaseous form by cooling the area from where molecule evaporated is said to be evaporation process. The vaporization process occurs only in 1 condition when the liquid boils above its boiling point.


Key Difference

  • Vaporization occurs during the boiling or sublimation process whereas the Evaporation process mostly occurs below the boiling point of the liquid.
  • Vaporization changes the state of matter from solid or liquid to the gaseous state whereas Evaporation used to change the liquid directly to the gaseous state.
  • Vaporization requires less energy and it is a fast process whereas Evaporation is the slow process.
  • All water changes in the gaseous state in the vaporization process whereas in evaporation water from the top change in the gaseous state.
  • During the process of Vaporization molecules come from below to the surface during boiling whereas, during the process of Evaporation, molecule vaporizes from the surface of the water.


What is the difference between Conductor and Insulator?

The main difference between the conductor and insulator is that Inductor allows the energy (current and heat) to pass through it. In the conductors, electron freely moves in the outer shell and the conductivity of the conductor depends on the number of electrons freely move in the outer shell.

Whereas the insulator does not allow the energy (heat and energy) to pass through it. Between the atoms of insulators, a covalent bond stronger due to which atoms cannot move freely and the resistivity is high in the insulators. To separating the conductors, insulators are used mainly.


Key difference

  • Conductor permits heat and current to pass through it whereas insulator does not permit heat and current to pass through it.
  • On the surface of the conductor, the electric field exists but remains zero inside the conductor whereas, in the case of insulators, the electric field does not exist in the insulators.
  • In conductors, the magnetic field store energy whereas in insulators magnetic field does not store energy.
  • Potential remains the same on all points in the conductor whereas in the insulator potential remains zero.
  • Thermal conductivity has by conductors whereas it not have by insulators.
  • The covalent bond is weak in the conductors whereas strong in the insulators.
  • Conductors have low resistance whereas insulators have high resistance.
  • Electron freely moves in the conductors but cannot freely move in the insulators.
  • Iron, copper, and silver are examples of conductor and Rubber, wood, and paper are examples of insulators.
