Question

A closed vessel 10L in volume contains a diatomic gas under a pressure of `10^5N//m^2`. What amount of heat should be imparted to the gas to increase the pressure in the vessel five times?

Answer 1

Correct Answer - A::D
`V=` constant
From `p_V=nRT`,
`VDeltap=nR(DeltaT)`
`Q=nC_VDeltaT`
`=n(5/2R)DeltaT=5/2(VDeltap)`
`=5/2xx(10xx10^-3)(4xx10^5)`
`=10^4J`
