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

Answer 1

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

The transition #"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 #"latent heat of fusion of ice"#.

When ice melts to give water, the temperature profile remains static because the energy being supplied is utilized for breaking the intermolecular bonds within the ice lattice, converting it into water, rather than increasing the temperature of the system. This phenomenon is known as the latent heat of fusion.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
