Home » Thermal Physics » Thermodynamics » Question

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

1. 2
2. 5
  3
3. 3
  2
4. 4
  3

Correct Option: C

According to question P ∝ T³
But as we know for an adiabatic process the

pressure P ∝	γ
	T^{γ - 1}

So ,	γ	= 3 ⇒ γ =	3	or,	C_p	=	3
	γ - 1		2		C_v		2
