MCQ
Which one is the correct option for the two different thermodynamic processes ?
- A$(c)$ and $(a)$
- ✓$(c)$ and $(d)$
- C$(a)$ only
- D$(b)$ and $(c)$
✓
Answer
Correct option: B.
$(c)$ and $(d)$
b
Option $(a)$ is wrong ; since in adiabatic process $V \neq$ constant
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 $\frac{ T ^{\gamma}}{ p ^{\gamma-1}}= constant$
