The internal energy of monoatomic ideal gas is 1.5 nRT. One mole of helium is kept in cylinder of cross section `8.5cm^2`. The cylinder is closed by a light frictionless piston. The gas is heated slowly in a process during which a total of 42 J heat is given to the gas. If the temperature rises through `2^@C` find the distance moved by the piston. Atmospheric pressure`=100kPa`n.
