Question

Match each vocabulary term on the left with its definition on the right.

1) volatility
2) vapor pressure
3) standard pressure
4) external pressure
5) normal boiling point
6) fusion
7) vaporization
8) sublimation

Answer 1

Vapor pressure is the pressure exerted by a vapor in equilibrium with a solid or liquid at a given temperature. The boiling point is the temperature at which the vapor pressure of a liquid equals the surrounding pressure. Fusion, vaporization, and sublimation are processes of changing states of matter.

Step-by-step explanation:

Vapor pressure is the pressure exerted by a vapor in equilibrium with a solid or liquid at a given temperature. It increases as temperature increases. Boiling point is the temperature at which the vapor pressure of a liquid equals the surrounding pressure. The normal boiling point is the temperature at which the vapor pressure is 760 torr or 1 atm.

Fusion is the process of changing from a solid to a liquid state. Vaporization is the process of changing from a liquid to a gaseous state. Sublimation is the process of changing from a solid directly to a gaseous state. External pressure refers to pressure exerted on the system from outside sources. Standard pressure is the atmospheric pressure at sea level.
