Chemical Engineering > GATE 2019 > Entropy Change
One mole of an ideal gas is contained in one part of a rigid, perfectly insulated container partitioned by a thin membrane; the other part is evacuated.
The initial pressure and temperature of the gas are Pi and Ti respectively.
The membrane ruptures and the gas expands to fill the entire volume; the final equilibrium pressure is Pf = Pi/4.
Given molar heat capacities Cp, Cv and the gas constant R (all in the same units as molar entropy), find the change in molar entropy Sf β Si.
