1 mol of an ideal gas is compressed to half of its initial volume (i) isothermally and (ii) adiabatically. Draw the p-V diagram in each case and hence state with reason, in which case the work done in less.

Text Solution

Verified by Experts


The slope of the adiabatic curve is more than the isothermal curve.
Work done in isothermal process = - area of ABCD and the work done in adiabatic process = -area of ABCE.
Compression will be less.
