`2.00 mol` of a monoatomic ideal gas `(U=1.5nRT)` is enclosed in an adiabatic, fixed , vertical cylinder fitted with a smooth, light adiabatic piston.The piston is connected to a vertical spring of spring constant `200 N m^(-1)` as shown in .The area of cross section of the cylinder is `20.0 cm^(2)`. Initially, the spring is at its natural length and the temperature of the gas is is `300 K`. The atmosphere pressure is `100 KPa`. The gas is heated slowly for some time by means of an electric heater so as to move the piston up through `10 cm`. Find
(a) the work done by the gas
(b) the final temperature of the gas and
(c ) the heat supplied by the heater.

Find the new height (in m) of the piston above the base of the cylinder.

A fixed container is fitted with a piston which is attached to a spring of spring constant k . The other and of the spring is attached to a rigid wall. Initially the spring is in its natural length and the length of container between the piston and its side wall is L . Now an dideal diatomic gas is slowly filled in the container so that the piston moves quasistatically. It pushed the piston by x so that the spring now is compressed by x . The total rotaional kinetic energy of the gas molecules in terms of the displacement x of the piston is (there is vacuum outside the container)
