A metal melts at 450 degrees celsius is the property of the metal classified as chemical or physical property?
chemical. when it melts, it doesn't mean it changed into a new substance. it just changed physical states! it is still a metal. physical state is a physical property of any substance, so when it changes physical state, as in changes to liquid, solid or gas, it is still the same substance.
Why is melting metal a physical change?
Melting metal is a physical change because it does not change the composition of the metal. The metal goes from a solid state to a liquid state, but it is still the same substance with the same chemical makeup.
What is a chemical and physical properties of francium?
1. Francium is the most reactive metal.2. The estimated melting point is 30 oC.
Is the melting of iron a chemical change?

When sodium metal melts to a liquid at 98 degrees is it a physical or chemicsl property?
The melting of sodium metal to a liquid at 98 degrees is a physical property. This is because it involves a change in state from solid to liquid without altering the chemical composition of the substance.
