Q. A jet of steam at 150 °C is directed at a large block of ice for some time at 0 °C. Some steam condenses to form water and some ice is melted. The condensed steam forms 0.6 kg of water at 0 °C. The specific latent heat of water is 2200 kJ kg⁻¹. What is the thermal energy given out by this mass of steam in changing to water at 100 °C?
