Heat Capacity

How do you differentiate which heat capacity to use in a problem?

I believe that if you are given mass or the number of moles in a problem, you should use the specific heat capacity (J x K^-1 x g^-1). Deciding which of the two equations to use (q = (heat capacity)(delta T) or q = (moles or grams)(specific heat capacity)(delta T)) can also help you determine which heat capacity to use.

Hi!
As Elizabeth said above, solving for heat capacity is very different since each problem varies upon what details it gives you. To better explain, since I don't want to chop up the words,

this website will help very much as it did for me!

Good luck this quarter,
Cecilia
