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.
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.
Melting is a physical property.Any thing is a physical property if it can be reversed but a chemical property can't.For e.g If you melt ice it will become water but still you can freeze it and form ice again. * * * * * Not true. Many chemical reactions are reversible.
When sugar caramelizes on being heated above its melting point, it undergoes a chemical change. This is because the heat causes the sugar molecules to break down and rearrange into new compounds, resulting in the formation of caramel.
A melting point is considered a physical property because it is a characteristic of a substance that can be observed without changing its chemical composition. It is the temperature at which a solid substance changes to a liquid state.
Yes, melting point is a physical property, not a chemical property. It is a characteristic of a substance that can help identify and differentiate it from other substances based on how it changes states from solid to liquid.
A melting point is a physical property. It yields much information in the identification of a compound
Physical--- melting something doesn't change its chemical composition.
Melting point is a physical property, not a change.
physical.
It is a physical property, so is boiling point.
No it is a chemical change
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.
The melting point is a physical property of materials.

Melting point is a physical property
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.
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.
