Task id12900
In a cylindrical vessel under the piston there is water vapor at a temperature of 100 ° C and an external pressure of 1 atm. The initial volume of the vessel is 20 l. At constant external pressure, the piston is lowered, so that the volume of Steam is halved. How much heat must be removed from the vessel so that the temperature of the steam remains constant? Neglect the volume of condensed water. The heat of vaporization of water at 100°C is 2246 J/g.
