# When ice metals to give water why is the temperature profile STATIC with the ice still present?

Jun 7, 2017

Because ice undergoes a phase transition when it thaws to give water...........

#### Explanation:

The transition $\text{ice +"Deltararr"water}$ is strongly endothermic (even if both states are at $0$ ""^@C). Energy has to be put into the system to effect the transition, and break the bonds that exist in solid ice. Such energy may be quantitatively measured, and represents the $\text{latent heat of fusion of ice}$.
