5) Consider a 0.15 mol sample of ideal gas confined to acylinder volume of 1.25 Lby a piston. The constant external pressure applied on the pistonis 2.2 bar andthe temperature of the gas is maintained constant at 250 K by athermostat. Thegas expands after the rivets holding the piston are removed.Calculate a) the volume of the gas when the expansion iscomplete. b) the work done when the gas expands. c) the heat absorbed by the system
d)the total change in entropy.
