Hint:

In thermodynamic processes, the relationship between heat, work, and internal energy depends on whether the process is isobaric, isochoric, adiabatic, or isothermal.

Answer 1

The Correct Option is C

The relations for heat exchange and work done during thermodynamic processes are: 
- (A) Isobaric: In an isobaric process (constant pressure), the heat supplied to the system is equal to the work done by the system, i.e., \( \Delta Q = \Delta W \). 
- (B) Isochoric: In an isochoric process (constant volume), the change in heat is equal to the change in internal energy, i.e., \( \Delta Q = \Delta U \). 
- (C) Adiabatic: In an adiabatic process (no heat exchange), \( \Delta Q = 0 \). 
- (D) Isothermal: In an isothermal process (constant temperature), the change in heat is equal to the change in internal energy plus the work done by the system, i.e., \( \Delta Q = \Delta U + P \Delta V \). 

Thus, the correct answer is (3).
