40L of an ideal gas is allowed to expand isothermally against vacuum until the total volume becomes 20L the amount of heat absorbed in this expansion (in L atm) is :

2L of an ideal gas at a pressure of 10 atm expands isothermally into a vacuum until its total volume is 10L. (i) How much heat is absorbed and how much work is done in the expansion? (ii)How much heat is absorbed if this system expands againts a constant external pressure of 1 atm? (iii) How much heat is absorbed if the expansion is conducted reversibly at 298 K.

Two litres of an ideal gas at a pressure of 10 atm expands isothermally at 25^(@)C into a vacuum until its total volume is 10 litres. How much heat is absorbed and how much work is done in the expansion ?

Three moles of an ideal gas at 127^(@)C expands isothermally untill the volume is doubled. Calculate the amount of work done and heat absorbed.

A gram molecule of a gas at 127^(@)C expands isothermally until its volume is doubled. Find the amount of work done and heat absorbed.

If 1.5 L of an ideal gas at a apressure of 20 atm expands isothermally and reversibly to a final volume of 15 L, the work done by the gas in L atm is:

In an isothermal expansion of one mole of an ideal gas against vacuum from 5 litre to 50 litre at 300 K, the quantity of heat absorbed by the gas is

One mole of an ideal gas is expanded freely and isothermally at 300K from 5L to 10L volume. If Delta E =0 , then Delta H is

5mol of an ideal gas at 27^(@)C expands isothermally and reversibly from a volume of 6L to 60L . The work done in kJ is
