Question

During an adiabatic process, the pressure of a gas is found to be proportional to the cube of its temperature. The ratio cpcvcpcv for the gas is :

Answer 1

For an adiabatic process the relation between T and P is

where γ = Cp /Cv

here P proportional to T^2

Then γ/(1- γ) = 2

Which gives 2= 3* γ

γ = 2/3
