Olympic sizes swimming pools are 50m long, 25m wide, and on average 2.5m deep. When they are initially filled with water the water will usually have a temperature of 15C How much energy is required to heat the swimming pool to the standard competition temperature of 27C? Provide your answer in Giga-joules with one decimal place accuracy. You may assume that no energy is lost through the walls of the pool and use a Cp of 4kJ/(kg.degree) Assume the density of water is 1000kg/
