(a). A vertical cylinder of height 100cm contains air at a constant temp. The top is closed by a frictionless piston . The atm. pressure is equal to75 cm of mercury . Mercury is slowly pour over piston.Find maximum height of mercury column that can be put on the piston.(b)A container of volume 50cc contains air (mean molecular weight =28.8gm)and is open to atmosphere where the pressure is 100kPaThe container is kept in bath containing melting ice(0 degree)1.find mass of the air in the container when thermal equilibrium is reached2. the cotainer is now placed in another bath containingboiling (100degree)find mass of air in the container
