Question

Assertion(A): During an adiabatic process, heat energy is not exchanged between system and its surroundings.

Reason(R): The temperature of a gas increases when it undergoes an adiabatic expansion.

• A. Both A and R are true and R is the correct explanation of A.
• B. Both A and R are true but R is not the correct explanation of A.
• C. A is true but R is false.
• D. Both A and R are false.

Answer 1

The correct option is C A is true but R is false.

$T{V}^{r-1}=$ constant for diabatic process
In an adiabatic expansion, temperature may increase or decrease depending upon the value of r.
For an adiabatic process, q $=$0.
