When a gas expands at constant temperature, why does the pressure decrease? Explanin it on the basis of kinetic theory of gases.
One mole of a gas is carried through the cycle shown in Fig. The gas expands at constant temperature T from volume V to 2V . It is them compressed to the initial volume at constant pressure and is finally brought back to its original state by heating at constant volume. Calculate the work done by the gas in complete cycle.
One mole of an ideal gas expands at a constant temperature of 300 K from an initial volume of 10 litres to a final volume of 20 liters. The work done in expanding the gas is (R=8.31 J// "mole"-K) (in joules)
