Homework Help: Heat Capacity v Specific heat capacity?

  1. Nov 5, 2011 #1
    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! :smile:

    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.
