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 gasA. is positiveB. is negativeC. is zeroD. may be positive

Answer» Correct Answer - 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
