Specific Heat Problems Q = mCpT Units are Joules (J)

1. How much heat is needed to raise the temperature of 400 grams of water from 0.0 C
to 15 C the Specific Heat of water is 4.186 J/gC?
A(Asking) – Q =?
G(Giiven) – m=400g, Cp = 4.186 J/g C, T = 15.0 C- 0.0 C =15 C
E(Equation) – Q= mCpT
S(Substitute & Solve) – Q = (400 g)(4.186 J)(15 C) =
