Work done by the Gas

A : Work done by a gas in isothermal expension is more than the work done by the gas in the same expasion adiabatically. R : Temperature remains constant in isothermal expansion and not in adiabatic expansion.

P-T curve of a cyclic process is shown. Find out the works done by the gas in the given proces if number of moles of the gas are n.

Assume the gas to be ideal, the work done on the gas in taking it from A to B is

Work done on an ideal gas in a cylinder when it is compressed by and external pressure in a single step is shown below : Which of the following graphs will show the work done on the gas ?

StatementI: Work done by a gas in isothermal expansion is more than the work done by the gas in the same expansion adaibatically. Statement II: Temperature remains constant in isothermal ecpansion but not in adiabatic expansion.

In a process, the pressure of an ideal gas is proportional to square of the volume of the gas. If the temperature of the gas increases in this process, then work done by this gas

Work done by a gas in a given process is -20J . Heat given to the gas is 60J. Find change in internal energy of the gas.
