Question

An insulated container of gas has two chambers separated by an insulating partition. One of the chambers has volume V₁ and contains ideal gas at pressure P₁ and temperature T₁ . The other chamber has volume V₂ and contains ideal gas at pressure P₂ and temperature T2 . If the partition is removed without doing any work on the gas, the final equilibrium temperature of the gas in the container will be

Answer 1

(b) : As this is a simple mixing of gas, even if adiabatic conditions are satisfied, PV = nRT for adiabatic as well as isothermal changes. The total number of molecules is conserved.
