Question:
In which process, heat exchange between the system and its surrounding does NOT take place?
In which process, heat exchange between the system and its surrounding does NOT take place?
Show Hint
Remember: Isothermal = Constant temperature; Isobaric = Constant pressure; Isochoric = Constant volume; Adiabatic = Zero heat transfer ($Q=0$).

The Correct Option is C
Solution and Explanation
Step 1: Understanding the Concept:
Thermodynamic processes are classified based on energy and mass exchange across the system boundary.
Step 2: Detailed Explanation:
An adiabatic process is strictly defined as a thermodynamic change occurring without any heat transfer across the system boundary ($\delta Q = 0$).
Any change in the system's state or temperature is driven entirely by mechanical work done on or by the system ($dU = -\delta W$).
Step 3: Final Answer:
Thus, in an adiabatic process, heat exchange between system and surroundings does not occur.
