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 21 J of heat energy is supplied to an ideal diatomic gas at constant pressure, then the change in its energy is

If 21 J of heat energy is supplied to an ideal diatomic gas at constant pressure, then the change in its energy is

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 sample of ideal gas (gamma = 1.4) is heated at constant pressure. If an amount 140 J of heat is supplied to the gas, find (a) the changes in internal energy of the gas, (b) the work done by the gas.

A sample of diatomic gas is heated at constant pressure. If an amount of 280 J of heat is supplied to gas, find ratio of work done by gas and change in internal energy

One cubic metre of an ideal gas is at a pressure of 10^5 N//m^2 and temperature 300K. The gas is allowed to expand at constant pressure to twice its volume by supplying heat. If the change in internal energy in this process is 10^4 J, then the heat supplied is

50 J heat is supplied to a gaseous system, simultaneously the gas expands against external pressure 2 atm by 0.8 L. The change in internal energy of the system will be
