Athermal isolated container has a content of 2.00 l water at a temperature 50°c. the container has a small opening to the environment, so the pressure is constant 1.00 atm. a block of iron at the temperature tron and the mass no heat transfer between the iron block and the environment or the container during the transport or afterwards). when thermal equilibrium has been reached 10 % of the water mass has evaporated. 3.00 kg is then put into the container (there is calculate the temperature tiron of the iron block before it was put into the container. a)
