Work done in the reversible expansion is

Which of the following expressions represent(s) work done by the isothermal reversible expansion of the ideal gas?

Work done by 3 mol of an ideal in an isothermal reversible expansion of 30^(@)C is 9.5 kJ. If the initial volume of the gas is 20 L, then what will be the final volume of the gas?

The change in entropy for 2 mol ideal gas in an isothermal reversible expansion from 10 mL to 100 mL at 27^(@)C is-

During an adiabatic reversible expansion of an ideal gas

The temperature of 4 mol of a gas decreases from 40^(@)C to -60^(@)C on adiabatic reversible expansion. The molar specific heat of the gas at constant volume being 12J*K^(-1)*mol^(-1) , determine the change in internal energy and work done in this process.

Two litres of an ideal gas at a pressure of 10 atm expands isothermally into a vacuum untill its total volume is 10 litres. How much heat is absorbed & how much work is done in the expansion ?

Write true or false of the following statements: No work is done during free expansion of an ideal gas under reversible or irreversible condition.

This question has Statement I and Statement II. Of the four choices given after the Statements, choose the one that best describes the two Statements. Statement-I : The magnitude of the work involved in an isothermal expansion is greater than that involved in an adiabatic expansion. Statement-II : P-V curve (P on y-axis and V on x-axis) decrease more rapidly for reversible adiabatic expansion compared to reversible isothermal expansion starting from same initial state.
