1 mole of an ideal gas is allowed to expand isothermally at `27^@C` until its volume is tripted. What is the value of `DeltaS` of universe when the expansion is carried out reversibly ?

One mole of an ideal gas at 300 K is expanded ‘ isothermally from an Initial volume of ( litre to 10 litre. What is the value of AE for 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 ?

Two litres of an ideal gas at a pressure of 10 atm expands isothermally into a vaccum until final volume is of 10 litres conducted reversibly. How much heat is absorbed ?

The volume of 1 mol of a gas is doubled when it expands isothermally at 127^(@)C . Find out the amount of work done and heat absorbed.

1 mole of an ideal gas expands isothermally reversible from 2 litre to 4 litre and 3 moles of the same gas expands from 2 litre to x litre and doing same work, what is 'x'-

Two mole of an ideal gas is expanded isothermally and reversibly from 1 litre to 10 litre at 300 K. The enthapy change (in kJ) for the process is

A 1.0 mol of ideal gas, initially at 10 atm and 300 K Is allowed to expand isothermally to 1.0 aim. as follows : Inversible expansion against 1.0 atm Determine the net work done by the system and describe the whole processes on p-V diagram.

Two identical containers A and B with frictionless pistons contain the same ideal gas at the same temperature and of volume. The mass of the gas in A is m_A and that same in B is m_g . The gas in each cylinder is now allowed to expand isothermally to the same final volume 2V. The change in the pressure in A and B are found to be Deltap and 1.5 Delta p respectively then
