The question asks which of these terms describe the heat best.
00:07
We know that the temperature, the internal energy, the internal energy, the radiant energy, and the final option that the internal energy that flows from hot to cold.
00:32
These all are in some sense contribute to the definition of heat but which one is the best description for the definition of heat let us understand what is the meaning of the word heat first in early days in ancient days heat was heat was assumed as some some other form of matter some new form of matter which which which this is as a thermal energy that that flows flows as a fluid from hot things to cold things hot things to cold things they believe that it is some kind of fluid that that flows from hot things to cold things so they were right that they were right about this part that heat flow from hot things to cold thing but it was not completely some form of matter.

Also the word heat means human perception of thermal energy.
01:51
Human perception of thermal energy and from the perception we know that when we perceive heat energy somewhere like this is some hot surface and and we keep our hands on it.
02:12
Temperature of our hand starts to increase and the heat from this hot surface start to transfer on our hand because our hand is in comparatively low temperature.
02:29
Therefore there is something which flows from here to here and that's why due to these heat current we perceive heat.

Now, according to the maxwell's study, what he found about the heat, first, the very first thing that it can be transferred from one body to another body, according to the second law of thermodynamic.
03:02
One body to another body.
03:09
The second conclusion he derived was it is some measurable quantity.
03:16
And can be treated mathematically...
