How much heat, expressed in Kwh, is required to raise the temperature of water in a 20,000 gallon pool by 10 degrees C. ?

heat=masswater*specificheat*10
masswater=20,000gal*8.3436lbs/gallon*1kg/2.2lbs
look up the specific heat of water in Joules/kg*C
then
Converting joules to kwh: 2.77777778 Ã— 107 j/kwh
Does that help?
