The given formula for heat, Q=mc (Tf-Ti), is the best way to solve such problems with changes in temperature. It can be said that m is the mass of the substance. C is the specific heat of the substance. The term (Tf-Ti) is the change in temperature.

Q = mc (Tf-Ti) = 480g (0.96 J/g-C) (234-22) = 97689.6 Joules of heat
