A melting point is a physical property. It yields much information in the identification of a compound
Melting point is a physical property, not a change.
No it is a chemical change
The melting point is a physical property of materials.
The change in the state of matter between solid, liquid and gas are not chemical changes. The melting point of a substance, silver in this case, is a physical characteristic.
Ice melting is a physical reaction, not a chemical one. It involves a phase change from solid to liquid as the temperature of ice increases above its melting point without any change in the chemical composition of the water molecules.
Physical--- melting something doesn't change its chemical composition.
Melting point is a physical property, not a change.
First of all, melting point is not a change at all, so forget about classifying it as a physical or a chemical change. It's a property and it's got nothing to do with the chemical composition of water since when water melts it's chemical nature does not change. Hence melting point of water is a physical property or characteristic.

It is a physical property, so is boiling point.

The melting of copper is a physical change because it involves a change in the state of matter from solid to liquid without altering the chemical composition of copper itself.
You could test the resulting liquid by determining its boiling point and melting point. If they are the same as the boiling and melting points for water, then it is probably water and a physical change rather than a chemical change has occurred.
