The specific heat of a certain type of metal is 0.128 j/(g·°c). what is the final temperature if 305 j of heat is added to 64.6 g of this metal initially at 20.0 °c?

When we add a certain amount of heat Q to a substance, the temperature of the substance increases by a  given by

where m is the mass of the substance and Cs is the  specific heat capacity of the substance.

By re-arranging the formula, we find


So, since the initial temperature of the metal is Ti=20 C, the final temperature is
