A gas may expand either adiabatically or isothermally. A number of p-V curves are drawn for the two processes over different ranges of pressure and volume, it will be found that (i) Two adiabatic curves do not intersect (ii) two isothermal curves do not intersect (iii) an adiabatic curve and an isothermal curve may intersect. (iv) the magnitude of the slope of an adiabatic curve is greater thanthe magnitude of the slope of an isothermal curve

StatementI: A gas is expanded from a volume V to 2V , first through adiabatic process then through isothermal process. Work done in isothermal process is more if final state (i.e. pressure and volume ) in both the cases is same Statement II: Work done by the gas is equal to area under p-V curve.

During a process carried on an ideal gas it was found that eta (lt 1) times the heat supplied to the gas is equal to increase in internal energy of the gas. Write the process equation in terms of pressure (P) and volume (V) of the gas. It is given that ratio of specific heats for the gas is (C_(P))/(C_(V)) = gamma .

Which of the following P-V curve best represents. As isothermal process?

If n moles of an ideal gas are expanded is isothermally and reversibly from an initial state in which it has pressure p_(1) and volume V_(1) to the final state of volume V_(2) and pressure P_(2) , then

An ideal gas intially has pressure P volume V and temperature T . Its is isothermally expanded to four times of its original volume, then it is compressed at constant pressure to attain its original volume V . Finally, the gas is heated at constant volume to get the original temperature T . (a) Draw V-T curve (b) Calculate the total work done by the gas in the process.(given ln2 = 0.693)

A gas expands from an initial state characterized by a pressure p_1 and a volume v_1 in two ways, isotherrnically and adiabatically, to the same volume v_2 In which of the two processes is the final pressure higher and in which is the work greater?
