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

• Physics -

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— 10-7 j/kwh

Does that help?
