Assertion (A): A thermodynamic system may be considered as a quantity ...
- But remember 100% heat can‟t be convertible to work but 100% work can be converted to heat. It depends on second law of thermodynamics.
- A thermodynamic system is defined as a definite quantity of matter or a region in space upon which attention is focused in the analysis of a problem.
- The system is a macroscopically identifiable collection of matter on which we focus our attention

Here the statement (R)is true because thermodynamics is a branch of science in this 'the work and heat are mutually convertable'. example: if aney machine is working some time after it will be heated.here work and heat are mutually convertible.

Assertion (A): A thermodynamic system may be considered as a quantity ...
Assertion and Reasoning Analysis:
Assertion (A):
- A thermodynamic system may be considered as a quantity of working substance with which interactions of heat and work are studied.
Reason (R):
- Energy in the form of work and heat are mutually convertible.
Explanation:
The assertion is false because a thermodynamic system is not just a quantity of working substance but encompasses the entire region under study in which interactions of heat and work take place. It includes boundaries and surroundings as well.
The reason is true as energy in the form of work and heat can be converted from one form to another. In thermodynamics, work done by a system can be converted into heat, and vice versa. This is known as the first law of thermodynamics, which states that energy cannot be created or destroyed, only transferred or converted from one form to another.
Therefore, the correct answer is option 'D' - A is false but R is true.
