Chemistry unit 3- Physical Properties of States of Matter

Boiling Point

-atmospheric pressure equals the vapor pressure of the liquid, causing liquid —> vapor

-bulk

-direct

Surface Tension/Cohesion

-inward force reduces the surface area of a liquid

-surface

-direct

Capillary Action/Adhesion

-liquid climbs the wall of a container because of imfs

-surface

-direct

Viscosity

-tendency of a liquid to resist pouring because of imf attraction to bulk solution

-bulk

-direct

Heat of Vaporization

-the energy in imfs that must be overcome for a liquid on the surface to vaporize (lq→ gas)

-bulk

-direct

Vapor Presssure

-the pressure of the vapor above the surface of a liquid

-surface

-inverse

Evaporation Rate

-how quickly a liquid will vaporize above the surface of a liquid

-surface

-inverse

Melting point

-temperature at which a solid and its liquid phase coexist in equilibrium, so the temperature where the solid melts (solid → liquid) or the liquid freezes (liquid → solid)

-bulk

-direct

Heat of Fusion

-amount of energy required to convert one mole of a solid into a liquid at its melting point

-bulk

-direct
