Task id12381

At temperature T=T0, a heavy piston tightly adjacent to the walls of a cylindrical vessel lies on a thin layer of liquid. The vessel is slowly heated. At temperature Т=ТЛ > Т0 the condition Ратм •S + Mg=Рsat•S is satisfied. where S is the cross-sectional area of the vessel, M is the mass of the piston, Ratm is atmospheric pressure, Psat is the saturated vapor pressure of the liquid, g is the acceleration of gravity. Show graphically the nature of the dependence of the height of the piston above the bottom of the vessel on temperature X(T). X=0 is the coordinate of the bottom of the vessel, X=X0 is the initial position of the piston.
