Expert Solution

Step 1

The melting point of a liquid is the temperature at which the liquid transforms from a solid to a liquid under atmospheric pressure. This is the point where the liquid and solid phases are equally present. The substance's melting point varies with pressure as well and is reported at standard pressure.
