Which of the following is not correct for a reversible adiabatic process?

A. $${\text{T}}{{\text{V}}^{\gamma - 1}}$$  = constant

B. $${{\text{P}}^{1 - \gamma }}.{{\text{T}}^{\text{Y}}}$$  = constant

C. $${\text{P}}{{\text{V}}^\gamma }$$  = constant

D. None of these

Answer: Option D

Solution(By Examveda Team)

An adiabatic process is represented by $$p{v^\gamma } = {\text{constant}}$$    now by replacing the $$p$$ with $$\frac{{nRT}}{v}$$  we get $$T{V^{\gamma - 1}} = {\text{constant}}$$    and by replacing the $$V$$ with $$\frac{{nRT}}{P}$$  we get the equation $${P^{1 - \gamma }}{T^\gamma } = {\text{constant}}.$$
