Boiling - is turning a liquid into a gas. Melting is turning a solid into a liquid.
The melting and boiling points of water are higher than those of a sugar water solution because the presence of sugar disrupts the hydrogen bonding between water molecules. This disruption lowers the melting and boiling points of the solution compared to pure water.
Melting and boiling are physical changes.
Melting: -259.14 C Boiling: -252.87 C
Elements have fixed melting and boiling points, while compounds have varying melting and boiling points depending on their composition. Mixtures do not have fixed melting and boiling points, as they are composed of multiple substances which each have their own individual melting and boiling points.
Melting point of iron=1535oC Boiling point of iron=2750oC
Melting: 700 C Boiling: 1737 C
No boiling is heating and energy is added and melting the solid turns into a liquid.
