Question

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)

Answer 1

Answer: (B)

Option (a) is wrong ; since in adiabatic
process $V\ne$ constant.
Option (b) is wrong, since in isothermal process
$T=$ constant
Option (c) $\&$ (d) matches isothermes $\&$
adiabatic formula :
$T{V}^{\gamma -1}=$ constant $\&\frac{T^{\gamma }}{p^{\gamma -1}}=$ constant
