When an ideal gas is compressed adiabatically and reversibly, the final temperature is:

A

higher than the initial

B

lower than the initial temperature

C

the same as the initial temperature

D

dependent on the rate of compression

Text Solution

Verified by Experts

The correct Answer is:
A
`DeltaU=q+W` if the process is adiabatic then q = 0, `Delta U =W ` i.e. increase in internal energy with work done on the system (compression) increase in temperature.
