How to find delta H of fusion

[Jaden Haskins 2E]

Is there a formula to find the delta H of fusion or is it calculated through q=mC△T and other similar formulas? In the specific problem I am working with, you are given amount of heat absorbed, mass, and T(initial).

[Charlotte Adams 1A]

I believe you are usually given the delta H of fusion or vaporization, at least thats how it was on the previous tests. Is this a book problem? Maybe you have to look at an appendix?

[Anh Trinh 1J]

You can also find delta H of fusion and vaporization on the equation sheet!

[Kelly Yun 2I]

I think that for the final, it would be given in the problem if we need the value for calculations..!

[Ethan Hung 2A]

Typically the enthalpy of fusion will be given in the question or in the equation sheet (in reality, it is experimentally determined). It cannot be calculated using q=mC△T as the temperature does not change during a phase change (the energy used to break intermolecular bounds as opposed to increasing the kinetic energy of molecules).

[Michael Crannell 1H]

Since the temperature doesn't change during the phase change because the energy is used solely for breaking apart molecules, the equation with delta T does not work since that value would be zero.
