Physical propertiesinclude: appearance, texture, color, odor, melting point, boiling point, density, solubility, polarity, and many others. The three states of matter are: solid, liquid, and gas. The melting point and boiling point are related to changes of the state of matter.
Web21 sep. 2024 · Boiling Point of a Substance A substance’s boiling point is a physical property. For instance, when water (H2O) boils, so when it converts from a liquid to a gas or water to steam, it is still water. The chemical identity is still H2O. The chemical property hasn’t changed, only its physical property. Is boiling water a physical property? WebA straight-chain alkane will have a boiling point higher than a branched-chain alkane due to the greater surface area in contact, and thus greater van der Waals forces, between adjacent molecules. For example, compare isobutane (2-methylpropane) and n-butane (butane), which boil at −12 and 0 °C, and 2,2-dimethylbutane and 2,3-dimethylbutane …
