Question

Which one is INCORRECT statement?

• A. In an isochoric process, volume remains constant
• B. In an adiabatic process, there is a heat exchange with the surrounding
• C. In an isobaric process, pressure remains constant
• D. In an isothermal process, temperature remains constant
• E. In a cyclic process, the change in internal energy is zero

Hint:

Adiabatic = No heat transfer ($Q=0$).

Answer 1

The Correct Option is B

Step 1: Concept
Verify the definitions of thermodynamic processes.

Step 2: Analysis
An adiabatic process is defined by the absence of heat transfer ($Q = 0$) between the system and its surroundings.

Step 3: Conclusion
Statement (B) incorrectly claims there is heat exchange; therefore, it is the incorrect statement. Final Answer: (B)
