Difference between heat and temperature with examples

In day-to-day life, we often use "heat" and "temperature" together and therefore it's now a common belief that they both are one and the same thing, but is it true?

Well if I have to tell you in short, then it's not and they are not the same thing. Heat and temperature are two different terms and things in the language of science.


Heat v/s Temperature
In this article, I am going to tell you how both these terms differ to each other and what are some real-life example which you can relate with to understand the difference more clearly.

Well if I had to tell you in short the difference between heat and temperature:

Heat is the amount of energy stored inside a body or object whereas temperature is the measurement of kinetic energy present inside a body or to say in a simpler term, it is the measurement of how cold or warm the body is. 

Heat v/s Temperature:

You will always notice that when you increase the amount of heat in a body its temperature also rises which gives a common belief that they both are the same. A very common example of this thing is, when you boil water the amount of heat inside water increases resulting in the rise in temperature of the water as well as its surrounding. 

I guess you are still not clear about the difference between both of them, well don't worry I am sure you will till the end of this article.

Just for time being think that heat is the energy which is present inside a body and the measurement of this energy is what you call temperature.


Heat v/s temperature
So when you increase the heat inside a body, its temperature rises and visa versa.

Refer to this table to get a clear difference between heat and temperature:

Sr.no Heat Temperature
1. Amount of energy inside a body. Measurement of the intensity of heat.
2. Sum of kinetic and potential energy in molecules in a body. Average of kinetics energy by molecules present inside a body.
4. Heat flows from the hotter object to cooler objects. The temperature rises in case of a hotter object and falls when cooled.
5. Heat is measured in unit joules and it's SI unit is also joules. Temperature is measured in celsius or kelvin but it's SI unit is kelvin.
6. Measured by a calorimeter. Measured by thermometer.
7. Two bodies having the same amount of heat can have different temperature. Two bodies at the same temperature can contain a different amount of heat.

As I have mentioned in my last point, imagine a condition where a two different bodies have the same amount of temperature but amount of energy carried by each of them will be different and if you increase the amount of heat in any one of them the overall temperature will rise as well because temperature is the measurement of kinetic energy inside a molecule.

If you think this in the microscopic world, so whenever there is an increase in heat of a body, atoms and molecules will gain kinetic energy due to which kinetic energy increases. 

And since the temperature is the measurement of the kinetic energy of molecules it will also rise resulting in increase of temperature.

This is how, whenever you increase the heat of a body it's temperature increases which often leads to a misunderstanding that heat and temperature are one and the same but that's not the case.
