An ideal gas expands from `500 cm^3` to `700 cm^3` against 1 atm pressure, by absorbing 2J of energy. Calculate change in internal energy of the ideal gas. 

Internal energy of an ideal gas depends upon

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

An ideal gas is heated from 20^(@)C to 40^(@)C under constant pressure. The change in internal energy is

The internal energy of an ideal gas is given by U = 1.5 PV. It expands from 10 cm^(3) to 20 cm^(3) against a constant pressure of 2 xx 10^(5) Pa. heat absorbed by the gas in the process is

The Volume of one mole of the gas is changed from V to 2V at constant pressure p. If gamma is the tatio of specific heats of the gas, change in internal energy of the gas is,
