What is the definition of boiling point in chemistry and how does it relate to the physical properties of a substance?
The boiling point in chemistry is the temperature at which a substance changes from a liquid to a gas. It is a physical property that is unique to each substance and can be used to identify and characterize it. The boiling point is influenced by the strength of intermolecular forces within the substance, with stronger forces requiring higher temperatures to overcome and boil.

Is a chemical property?
(combustibility)A chemical property is any characteristic that gives a substance the ability to undergo a change that results in a new substance.Example: Matches are permanently changed and black after they are burned. Therefore this property can be observed only by changing the composition of the match. Or for instance when you bake pie you put the ingredients in but never can take them out!The chemical property of a given element refers to the property that is used to characterize the reaction of the materials hence their identity.(combustibility)
