STANDARD Physics Adiabatic Processes MCQ Question
Type: MCQ-conceptual-Medium-Class 11
The possibility of increase in the temperature of a gas without adding heat to it happens in
A
adiabatic expansion
B
isothermal expansion
C
adiabatic compression
D
isothermal compression
Correct Answer
Option C
Detailed Explanation
In an adiabatic process, dQ = 0, so dU + dW = 0 or dU = -dW. During compression, work is done on the gas, making dW negative. Hence, dU is positive, increasing the internal energy and temperature of the gas.
