Chapter 3 Calorimetry - Specific Heat and Latent Heat
... When an object undergoes a phase transition, its internal energy changes, but its temperature does not. For example, as a piece of ice melts at 0o C, it becomes liquid water, which is also at 0o C. There is no temperature change, but energy (in the form of heat) must be added to the system to change ...
