In a process, the pressure of an ideal gas is proportional to square of the volume of the gas. If the temperature of the gas increases in this process, then work done by this gas

A

is positive

B

is negative

C

is zero

D

may be positive

Text Solution

Verified by Experts

The correct Answer is:
B

`P alpha 1/(V^(2))rArr P=k/(V^(2)) rArr P V^(2)=k`
`rArr PV.V=krArr nRTVrArr TV=k_(1)`
Since temperature increases therefore volume decreases
