MCQ
The specific heat of isothermal process is
- A$0$
- ✓$\infty $
- C$\frac{3}{2}\,R$
- D$\frac{5}{2}\,R$
✓
Answer
Correct option: B.
$\infty $
b
Given the process is isothermal which means it's temperature won't increase.
Given the process is isothermal which means it's temperature won't increase.
$C _p=\frac{\Delta Q }{ n \Delta T }$
Therefore specific heat will be infinity, as it is defined as heat supplied per unit increase in temperature.
