A jet of steam at 100degrees Celsius is directed on a large block of ice at 100 degrees Celsius for a short time. o.4 kg of steam condenses to form water and some ice is melted at 8 degrees Celsius. Calculate the heat given out by this mass of steam in converting to water without a change in temperature. calculate the heat given out by this steam in changing to water without change in temperature specific latent heat of vaporisation of water as 2200kj/kg ii calculate the heat given out by this water as it cools to the temperature of the ice heat capacity to be 4.2kj/kg
