When a gas is subjected to adiabatic expansion, it gets cooled due to :

A

Fall in temperature

B

Loss in kinetic energy

C

Decrease in velocity

D

Energy spent in doing work

Text Solution

Verified by Experts

The correct Answer is:
D
According to `I` law of thermodynamics:
`q=DeltaU+(-w)`. For isothermal expansion `DeltaU=0`
`:. q=-w`
