When finding the energies needed to increase the temp/change phase of a substance, I know to use the q=mcdeltaT equation to find the energy to raise the temp... but my question is about the equation for energy to change phase.
Which equation is correct to find the energy to change phase:
(1) q=m delta H where m is the mass in g
or
(2)q=n delta H where n is the number of moles
Chad says (2), TPR says (1), spraknotes on the internet say (1), other internet sources say (1) and (2)...
I feel like it should be (1) since the equation for the energy to raise temp uses m instead of n, but I never like to second guess Chad...haha
