Question

How does the kinetic theory of matter define heat.

Answer 1

Hint: To solve this problem we will discuss about the kinetic theory of matter, how the thermal energy of molecules associates with the heat and the means of transfer of heat between the systems containing ideal gas and to how much extent it differs from real gas molecules.

Complete answer:
Kinetic theory of matter explains a description of molecular properties such as pressure, volume and temperature and the change in phase according to the heat associated with them.
Kinetic theory states that:
All particles or molecules are associated with some energy which varies with temperature and type of matter, by which we can identify the state of matter (either solid liquid or gas).
When the energy of molecules varies phase may or may not be changed.
Molecules are associated with a force of attraction and these forces are known as intermolecular attraction.
Now, when two systems of an ideal gas are in contact with each other heat is transferred from one system to another but in kinetic theory the motion of molecules are responsible for this transfer of energy by colliding with each other and transferring energy from higher energy molecule to lower energy molecule.
In the kinetic theory we have a large number of identical or some non-identical gas molecules moving with very high speed in all directions exerting pressure and transferring energy from one molecule to another.

Note:
The above conclusions are made up by assuming potential energy to be zero by taking ideal gas in mind, but for real gases and practical condition there will be some amount of potential energy between ions and molecules which can affect motion and energy or heat transfer between the system.
