Calculate the work done for 1 mole of perfect gas during adiabatic process
Asked by shobhit_dc | 23 Sep, 2011, 03:16: PM
answered-by-expert Expert Answer
Consider one mole of a perfect gas in a cylinder fitted with a frictionless piston.
Let P1, V1, T1 be the initial pressure, volume and temperature of the gas. If P is pressure of the gas at any instant during expansion, ans A is area of cross section of the piston, force exerted by the gas on the piston is F = P x A
Assuming that the pressure of the gas duting an infinitesimally small outward displacement dx of the piston remains constant, small amount of work done during expansion is

During calculation of acceleration due to gravity above the surface of earth if we assume that there is an external force opposite to that of Earth's gravity then the cos angle will be 180 between the two forces which is negative(-1), if we put the value in the equation of dw = F.dx then the final value of potential energy is positive which is not possible.how and why??
