is the boiling point of a substance a chemical property

Best answer

The boiling pointis the temperature at which a substance converts from liquid phase to gas phase. And hence,boiling pointsand melting pointsare physical properties. Since they are a propertyof the material, they can be used to identify it.

  • What is a boiling point?

  • The boiling point of a substance is the temperature at which the vapor pressure of the liquid is equal to the surrounding atmospheric pressure, thus facilitating transition of the material between gaseous and liquid phases.

  • What are the physical and chemical properties of matter?

  • All substances have distinct physical and chemical properties, and may undergo physical or chemical changes. Physical properties, such as hardness and boiling point, and physical changes, such as melting or freezing, do not involve a change in the composition of matter.

  • Where do you find the boiling point on a safety data sheet?

  • You can often find it in the section 9 of a safety data sheet (SDS). Besides indicating the physical state (liquid or gas) of a substance at ambient or room temperature, boiling point serves as an indicator of volatility even for laymen, with higher boiling points indicating lower volatility.

  • Why boiling point test is not required for every chemical?

  • You probably do not want to store or transport a liquid at a temperature close to or above its boiling point in which case the boiling may cause leaking and severe consequences. Boiling point test is not required for every chemical.
