5 mol of gas at 5 atmospheric pressure contained in a 100 L cylinder absorbed 30.26 Kj of heat when it expanded to 200 L at 2 atmospheric pressure. The change in the internal energy of gas is

A gas is at 1 atm pressure with a volume 800 cm^(3) . When 100 J of heat is supplied to the gas, it expands to 1L at constant pressure. The change in its internal energy is

A gas is at 1 atm pressure with a volume 800 cm^(3) . When 100 J of heat is supplied to the gas, it expands to 1L at constant pressure. The change in its internal energy is

A gas is at 1 atm pressure with a volume 800 cm^(3) . When 100 J of heat is supplied to the gas, it expands to 1L at constant pressure. The change in its internal energy is

If a gas absorbs 200J of heat and expands by 500 cm^(3) against a constant pressure of 2 xx 10^(5) Nm^(-2) then change in internal energy is

A certain volume of a gas expands at one standard atmosphere pressure when 400 cal of heat is supplied to it. If there is no change in the internal energy of the gas, calculate its volume expansion.

A gas absorbs 100 calories of heat energy and is compressed from 10.0 L to 5.0 L by applying an external pressure of 2.0atm. The change in internal energy is

Frictionless and weightless piston was fitted into a cylinder containing a gas This gas was allowed to expand from one litre to 5 litre against a constant pressure of one atmosphere in doing so, 200 J of heat was absorbed from the surrounding . The change in the internal energy of the system is :
