Solve the following problem given below:
Problem: A vessel whose walls are thermally insulated contains 2.30kg of water and 0.400kg of ice, all at a temperature of 0.0 ?C. The outlet of a tube leading from a boiler in which water is boiling at atmospheric pressure is inserted into the water.
Part A: How many grams of steam must condense inside the vessel (also at atmospheric pressure) to raise the temperature of the system to 21.0?C ? You can ignore the heat transferred to the container.
Please explain your solution. I know substitution is involved so be sure to give a detailed explanation on that as well.
