Answer:
1.Melting point
Melting point as a chemistry concept
The solid begins to go from a solid state to a liquid state — a process called melting. The temperature at which melting occurs is the melting point (mp) of the substance. The melting point for ice is 32° Fahrenheit, or 0° Celsius.
2.When a liquid loses heat, it freezes to become a solid. When solid ice at 0°C is heated, it gains heat and melts to form liquid water. When a gas loses heat, it condenses to form liquid water. When a liquid gains heat, it evaporates to form a gas.
