with B * = I- B. This requires that one of the preceding equations be solved for P t. Solving the second equation for P t yields You can estimate the intercepts of a system of simultaneous equations ...

Melting and freezing are both physical changes, which are often easy to reverse. To reverse this process, the water would need to be cooled enough until it freezes back into ice. This works because ...
