q=nc delta t

Postby Dahriel Aron 3A » Sat Jan 23, 2016 11:24 pm

In the homework for chapter 8 I noted that sometimes in calculating q the book sometimes multiplied the specific heat and the change in temperature by the grams and and other times multiplied the specific heat and change in temp by mols and I was wondering why that is

Either way is ok, because the change in heat is given by the amount of a substance that you have, which can be given in terms of moles or grams. Just be sure to notice these differences on an exam, and calculate the heat using the proper units!
