Calculating Heat Energy Problems
How to calculate heat energy problems
• When we need to figure out how much heat (in joules) is gained or lost, we check out Reffy.
• Reffy, Table T (p. 12):
The left column shows us the heat formulas.
The columns to the right explain to us what each letter represents. • Let’s learn the first equation now: q=mC∆T
Plug the words into the equation:
heat=mass × specific heat capacity × change in temperature
