According to first law of thermodynamics, ΔQ = ΔU + ΔW = ΔU + PΔV. If heat is supplies in such a manner that volume does not change ΔV = 0 i.e., isochoric process, then whole of the heat energy supplied to the system will increase internal energy only. But, in any other process it is not possible. Also heat may absorbed or evolved when state of thermal equilibrium changes.

Assertion and Reason Explanation:
The correct answer is option 'D', which states that both the assertion and the reason are false. Let's break down the explanation:
Assertion:
- The assertion states that the heat supplied to a system is always equal to the increase in its internal energy. This is not entirely true because the heat supplied to a system can also be used to do work on the surroundings, in addition to increasing the internal energy of the system.
- Heat supplied to a system can result in an increase in internal energy, but it can also be utilized for other purposes such as performing mechanical work.
Reason:
- The reason provided states that when a system changes from one thermal equilibrium to another, some heat is absorbed by it. This statement is also incorrect because when a system changes from one thermal equilibrium to another, the heat flow may not necessarily be absorbed by the system.
- Heat transfer can occur from the system to the surroundings or vice versa, depending on the specific conditions of the process.
Therefore, both the assertion and reason are false as they oversimplify the relationship between heat transfer and internal energy changes in a system.
