How much time will it take to heat water

  1. Dec 15, 2014 #1
    1. The problem statement, all variables and given/known data
    T1= 20C
    T2=80C
    Power=2kW
    Volume= 10liters

    2. Relevant equations
    Q= Power x time
    Q= m x c x DELTA Temp

    3. The attempt at a solution

    Do I need another equation to be able to find the heat? Since I have the equation of the heat I have the mass and I have the temperature but the c I don't have it.
    I then can use the Q/P = t, to find t. What's the c exactly?

    You have been given the heat capacity of water in some context previously have you not?
