# Heat Capacity v Specific heat capacity?

1. The problem statement, all variables and given/known data
what is the different in term of definition between Heat capacity and Specific heat capacity ?

2. Relevant equations

Q=mΔTC →C=Q/mΔT

3. The attempt at a solution
Specific heat capacity is the amount needed per unit mass of material so is a number independent of the amount of material but Heat capacity deals with an arbitrary amount of material
is this the only different?

Hi nafo man!

You have it right!

Beyond that you have the molar heat capacity Cmol (amount needed for 1 mol of the material).
Usually the specific heat capacity is denoted with a lowercase c as opposed to the regular heat capacity and the molar heat capacity that are both denoted with an uppercase C.

So: Q = C ΔT = m c ΔT = n Cmol ΔT.
