Topic: Thermodynamics
In the polytropic process $PV^{n}=$ Constant, if $n=1$ the process will be at-
- A. Constant volume
- B. Constant pressure
- C. Constant temperature
- D. Adiabatic
Answer: C. Constant temperature
Explanation: Polytropic process $PV^{n}=$ Constant. If $n=1$, $PV^{1}=$ Constant. According to ideal gas law, $PV = mRT$, which means temperature is constant (Isothermal process).
