Which one is the correct option for the two different thermodynamic processes ?

A

$(c)$ and $(a)$

B

$(c)$ and $(d)$

C

$(a)$ only

D

$(b)$ and $(c)$

(JEE MAIN-2021)

Solution

Option $(a)$ is wrong ; since in adiabatic process $V \neq$ constant

Option $(b)$ is wrong, since in isothermal process

$T = constant$

Option $(c)$ and $(d)$ matches isothermes and adiabatic formula :

$TV ^{\gamma-1}=$ constant and $\frac{ T ^{\gamma}}{ p ^{\gamma-1}}= constant$
