Obtain expression for the work done by an indeal gas during isothermal change .

Obtain an expression for the work done by an ideal gas during adiabatic change and explain .

A gas expands from 40 litres to 90 litres at a constant pressure of 8 atmosphers. Work done by the gas during the expansion is

A gas expands from 10 litre to 20 litre at a constant pressure of 2 atmospheres. What is the work done by the gas during the expansion ?

An ideal gas goes from the state I to to the state f as shown in figure. The work done by the gas during the process

In a cyclic process shown in the figure on ideal gas is adiabatically taken from B to A, the work done on the gas during the process B rarr A is 30J, when the gas is taken from A rarr B the heat absorbed by the gas is 20J. What is the change in internal ebergy of the gas in the process A rarr B .

An ideal gas expands isothermally from volume V_(1) to volume V_(2) . It is then compressed to original volume V_(1) adiabatically . If p_(1),p_(2) and W represent the initial pressure , final pressure and the net work done by the gas respectively during the entrie process, then
