wk 5 hw 3

Classify the phase changes by the signs of the system's H and S.

H=+ and S=+ H=+ and S=- H=- and S=+ H=- and S=-

Is there a way to better remember the different phases changes by looking at the signs?

For phase change increasing in energy such as melting, both are positive. Vice versa.
