When a gas is compressed adiabatically and reversibly, the final temperature is -

A

Higher than the initial temperature is -

B

Lower than the initial temperature

C

The same as initial temperature

D

Dependent upon the rate of compression

Text Solution

Verified by Experts

The correct Answer is:
A
For adiabatic process `-Delta E = W`
`nC_(V).Delta T = -ve`
`rArr Delta T = -ve`
`rArr T_(2)lt T_(1)`
