Melting point of Copper is 1084.62C. Note that, these points are associated with the standard atmospheric pressure. In general, melting is a phase change of a substance from the solid to the liquid phase.

The melting point of a substance is the temperature at which this phase change occurs. The melting point also defines a condition in which the solid and liquid can exist in equilibrium. Adding a heat will convert the solid into a liquid with no temperature change.

Matter is capable of undergoing changes, which are classified as either physical or chemical. Physical changes in matter are reversible: An ice cube can melt into liquid water, and then the liquid water can be frozen back into an ice cube.

As a result, brass represents a physical change instead of a chemical change. Remember that a physical change is a change in properties such as texture, shape, or state, while a chemical change represents the formation of a new substance after atoms are rearranged in a chemical reaction.
