List of top Physics Questions on Thermodynamics terms asked in MET

An engine has an efficiency of \( \frac{1}{3} \). The amount of work this engine can perform per kcal of heat input is :

During an adiabatic process, the pressure P of a fixed mass of an ideal gas changes by \( \Delta P \) and its volume V changes by \( \Delta V \). If \( \gamma = C_P/C_V \), then \( \Delta V/V \) is given by:

In the indicator diagram, AB is an isotherm and BC is an adiabat, because :

Internal energy of a gas remains unchanged in:
I. an isothermal process
II. an adiabatic process
III. a reversible process
IV. a cyclic process

Which equation is valid for adiabatic process?
