The enthalpy of vaporization of water is 40.79 kJ/mol. How much heat is required to vaporize 2 moles of water at its boiling point?
Which is an adiabatic process?

In which thermodynamic process, there is no exchange of heat between the system and surroundings?

Under isothermal conditions a gas expands from 0.2 dm3 to 0.8 dm3 against a constant pressure of 2 bar at 300 K. Find the work done by the gas.(1 dm3 bar = 100 J)

In an adiabatic expansion of a gas initial and final temperatures are T1 and T2 respectively then the change in internal energy of the gas is [R = gas constant, γ = adiabatic ratio]
