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 × 10-7 j/kwh

    Does that help?
