Heat Capacity

Postby Courtney McHargue 1I » Mon Jan 28, 2019 7:27 pm

Since heat capacity and specific heat capacity are one calculation apart, when asked about heat capacity in a question should we assume they're asking about specific heat capacity? Will normal heat capacity ever be asked about?

I think it would depend on the information the question gave you. I'm guessing that if it gave you the amounts of substances in moles they would wan the answer in the form of specific heat capacity (kJ*(degrees C)-1*g-1).

Usually they'll give you units for everything so if there are grams in the units then use specific heat capacity and if there are moles use molar heat capacity

It should be made very clear whether or not you are looking for heat capacity or specific heat capacity. If units of mass are given at any point in a problem then you are probably looking for specific heat capacity.

When they ask you the question the information should be enough for you to determine whether or not to calculate specific, molar, or just plain heat capacity

This honestly depends on the question being asked. Given units and a period table, you should be able to know whether to convert or not to match the question. Just read carefully and fully understand what's being asked for and how you will get there.
