How much time will it take to heat water

[cycrups]

Homework Statement

T1= 20C
T2=80C
Power=2kW
Volume= 10liters

Homework Equations

Q= Power x time
Q= m x c x DELTA Temp

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?
