). 25 kg of molten Aluminium, at a temperature of 800 °C, is poured into a pool of water. The pool contains 2000 litres of water at 15 °C. The following table provides useful values:

(a) the heat lost by the liquid aluminium as it cools from 800 °C to its melting/freezing point of 660 °C.[1 monk] (b) the heat lost by the aluminium to turn from a liquid to a solid. =) the temperature of the water after the Aluminium has completely solidified. (d) the temperature at which the water and (now solid) aluminium will come to equilibrium
