Question 8.41

Postby Cassidy 1G » Sun Jan 21, 2018 8:06 pm

Why do we have to find both the enthalpy of fusion of the ice and the heat (q=gCs deltaT) of the ice and then add them?

We do this because you need to account for the phase change as a separate entity and then you also do the q= mCdeltaT for the temperature change and add these energies together. It requires much more energy to create a phase change then just to simply raise the temperature.
