Specific Heat Capacity Question

  1. Jan 21, 2010 #1
    A bath contains 110 litres of water where 1 litre has a mass of 1kg.

    a) Given that the specific heat capacity of water is 4200JKg-1K-1, calculate the energy required to raise the temperature of the water from 10'C to 40'C.

    b) As the water flows through the copper pipes, it is heated from 10'C to 40'C by a gas flame The water flows at 5kg per minute. Calculate the rate of energy transfer to the water.

    Attempt:
    a) Q=mcT
    Q=30 x (110X4200)
    Q= 1.38X107J

    b) Rate of energy transfer = Power
    Power = W/t ???
