Enthalpy

Is the enthalpy (H) of liquid water greater than that of the same quantity of ice at the same temperature?

Not sure. Question is

The enthalpy (H) of liquid water is greater than that of the same quantity of ice at the same temperature. True or False?

How is it possible that both liquid water and ice can be at the same temperature?

The enthalpy of fusion will be the change in enthalpy during the fusion.

Have you ever seen mixture of water and ice, having temperature of the melting point?

Yes I am aware of that....I was referring to ice and water that are independent of each other.

Where is the problem with separating them WITHOUT changing temperature of each?
