Learn about physical and chemical properties. Understand what they are, the difference between them, and the physical and chemical properties of matter. Related to this Question What would be the effect of either increasing or decreasing the pressure over...
the others. These properties can be chemical or physical. Chemical properties describe how substances react with one another other, whereas physical properties are observations based on the identity or composition of a substance. Boiling is aphysical changeand a boiling point is aphysical property. ...
Boiling begins when the liquid is heated to the point at which the pressure of the saturated vapor above its surface becomes equal to the external pressure. The temperature at which a liquid starts to boil under a constant pressure is called the boiling point (Tb). Strictly speaking, Tb ...

Is boiling point a physical property? Yes, a substance's boiling point is a physical property. A physical property is a characteristic of a substance that can be observed or measured without changing the chemical identity of the substance. What’s the boiling point? The boiling point of a su...
It is a physical property that is different for every compound or substance, thus it can be used as an identification parameter. It is always useful and almost obligatory to know the boiling of substances before making any chemical reaction or synthesis. Particularly, the boiling point of ...
The initial boiling point is one of the characteristics of oils and fuels that relates to their volatility and, thus, indirectly to their tendency to be ignited by an external heat source. The volatility of an oil or fuel depends on its chemical composition. There are many indicators for asse...
and water is greater than that of pure water. boiling point elevation is a colligative property of matter, i.e. it is dependent on the solute-to-solvent ratio but not on the solute’s identity. this implies that the elevation in the boiling point of a solution depends on the amount of...
