Boiling point is thetemperature at which the vapor pressure of a chemical equals atmospheric pressure. To simply put,it measures the temperature at which a chemical boils. Similar to melting point,a higher boiling point indicates greater inter-molecular forces and therefore less vapour pressure.
People also ask
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.
What characteristics enable us to distinguish one substance from another?
The characteristics that enable us to distinguish one substance from another are called properties. A physical property is a characteristic of matter that is not associated with a change in its chemical composition. Familiar examples of physical properties include density, color, hardness, melting and boiling points, and electrical conductivity.
What are some examples of chemical properties?
The change of one type of matter into another type (or the inability to change) is a chemical property. Examples of chemical properties include flammability, toxicity, acidity, reactivity (many types), and heat of combustion. Iron, for example, combines with oxygen in the presence of water to form rust; chromium does not oxidize ( Figure 2 ).
