A gas is allowed to expand in an insulated container against a constant external pressure of 3 atm from an initial volume of 5.0L to final volume of 9.0L .The change in internal energy `Delta U` of the gas is

A gas is allowed to expand in a well insulated container against a constant external pressure of 2.5 atm from an initial volume of 2.50 L to a final volume of 4.50 L . The change in internal energy Delta U of the gas in joules will be:

A gas expands in an insulated container against a constant external pressure of 1.5 atm from an initial volume of 1.2 L to 4.2 L. The change in internal energy (deltaU) of gas is nearly (1 L-atm = 101.3 J)

An ideal gas is allowed to expand from 1L to 10 L against a constant external pressure of 1 bar. The work doen in kJ is:

An ideal gas is allowed to expand from 1 L to 10 L against a constant external pressure of 1 bar. Calculate the work done inkJ.

A gas expands isothermally against a constant external pressure of 1 atm from a volume of 10 dm^(3) to a volume of 20 dm^(3) . It absorbs 800 J of thermal energy from its surroundings. The Delta U is
