A tube leads from a 0.150 kg calorimeter to a flask in which water is boiling under atmospheric pressure. The calorimeter has specific heat capacity 420 J/(kg?K), and it originally contains 0.340 kg of water at 15.0 ?C. Steam is allowed to condense in the calorimeter at atmospheric pressure until the temperature of the calorimeter and contents reaches 71.0 ?C, at which point the total mass of the calorimeter and its contents is found to be 0.525 kg.

Compute the heat of vaporization of water from these data. Kindly write the working equation and the step-by-step solution for this problem.

A vessel whose walls are thermally insulated contains 2.20 kg of water and 0.450 kg 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 25.0 ∘C ? You can ignore the heat transferred to...
