A jet of steam at 100β is directed for a short time on to a large block of ice at 0β. Some of the steam condenses to form water and some ice is melted. The condensed steam forms 0.40 kg of water at 0β.
Questions:
1. Calculate the heat given out by this steam in changing to water without change in temperature. [Take the specific latent heat of vaporization of water as 2 200 kJ/kg].
2. Calculate the heat given out by this water as it cools to the temperature of the ice. [Take the specific heat capacity of water to be 4.2 kJ/(kg K).]β
