The solid changes into a liquid
It is indeed possible for a substance to have a higher melting point than expected. This normally happens when the substance is impure.
it melts
Nothing. Melting is a physical change and does not alter the chemical composition of a substance.
it decreases.
melting
Boiling occurs when a substance changes from a liquid to a gas at its boiling point, while melting happens when a substance changes from a solid to a liquid at its melting point. Both processes involve an increase in temperature that causes the substance's molecules to gain enough energy to overcome intermolecular forces and change states.
One substance that has a high melting point is diamond.
what the heck are you asking? the melting point is not a substance. it's a temperature in which the substance starts to melt
It indicates that the substance has turned to a liquid.
It has reached its melting point.
The melting point of a substance is the temperature at which it changes from a solid to a liquid.
does the melting point of a substance change over time
