Enthalpy, or 
Example Question #32 : Thermodynamics
An ice cube melts into water. While it is melting, what is the temperature of the mixture doing?
The ice part of the mixture is colder than the water part.
The temperature fluctuates depending upon the point at which you measure it.
The temperature of the mixture steadily increases while melting.
The temperature of the mixture steadily decreases while melting.
It remains constant while melting.
It remains constant while melting.
When an object is changing forms (solid to liquid in this case), the temperature remains constant. All of the energy that would normally go towards changing the internal temperature of the object is going into the latent heat of fusion or enthalpy of fusion instead.
