Under a weightless piston in a cylinder there is 1 kg of water at a temperature of 0°C. A piece of iron weighing 1 kg, heated to a temperature of 1100° C, is lowered into water. To what height will the piston rise? Atmospheric pressure 1 atm, specific heat capacity of iron C = 0.5 J/g • deg. Piston area S = 1000 cm2. Neglect heat transfer and heat capacity of the cylinder.
