A monoatomic gas at a pressure P , having a volume V expands isothermally to a volume 2 V and then adiabatically to a volume 16 V . The final pressure of the gas is: (take γ = 5 / 3 )

Question

A monoatomic gas at a pressure P , having a volume V expands isothermally to a volume 2 V and then adiabatically to a volume 16 V . The final pressure of the gas is: (take γ = 5 / 3 ), 64 P, 32 P, P / 64, 16 P

MARKS App · Accepted Answer

Isothermally P V = P 1 2 V P 1 = P 2 Adiabatically P 2 2 V γ = P f 16 V γ P f = P 2 1 2 3 5 3 P f = P 2 1 2 3 5 3 = P 2 2 5 P f = p 64
