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?
