List of top Physics Questions on Laws of thermodynamics asked in NEET (UG)

The correct option for free expansion of an ideal gas under adiabatic condition is :
A sample of 0.1 g of water at 100°C and normal pressure (1.013 × 105 Nm-2 ) requires 54 cal of heat energy to convert to steam at 100°C. If the volume of the steam produced is 167.1 cc, the change in internal energy of the sample, is
During an adiabatic process, the pressure of a gas is found to be proportional to the cube of its temperature. The ratio of Cp/Cv for the gas is
The molar heat capacity of water at constant pressure, $C$, is $75\, JK ^{-1}\, mol ^{-1}$. When $1.0\, KJ$ of heat is supplied to $100\, g$ of water which is free to expand, the increase in temperature of water is :
