Dear Charlie:

Your wrote: **"I need the formula as well as the answer"**, we don't the homework...please I recommend you the following steps:

1- Try to search on Google

2- As wrote ARGOS:**There are a Lot of such answers on the Forums!**...SEARCH

3- Read the Forum rules before posting

So, Let me give you a hint:

When heat is transferred to an object, the temperature of the object increases. When heat is removed from an object, the temperature of the object decreases. The relationship between the heat ( q ) that is transferred and the change in temperature (ΔT) is

q = C ΔT = C (Tf-Ti)

The proportionality constant in this equation is called the heat capacity ( C ). The heat capacity is the amount of heat required to raise the temperature of an object or substance one degree. The temperature change is the difference between the final temperature ( Tf ) and the initial temperature ( Ti ).
