Question

During the adiabatic process , the pressure of a gas is found to be proportional to the cube of its absolute temprature . the ratio of Cₚ /Cᵥ for the gas is [AIEEE 2003] ​

Answer 1

Answer:

3 / 2

Explanation:

P∝T³

,PV=nRT

P∝T³

P∝(PV)³

P² V³ =constant

PV × 3/2 =constant

γ= 3/2

Answer 2

Answer:

P∝T^3

PT^3 = constant...............(1)

γ/1-γ = (-3)

γ = −3+3γ

3 = 3γ−γ

γ = 3/2
