- Boyle’s law: the volume of a gas is inversely proportional to the pressure applied to it if the temperature remains constant.
- Gay-Lussac's law: the absolute temperature of a gas is directly proportional to the pressure if the volume remains constant.
- Avogadro's principle: Under conditions of constant temperature and pressure, equal volumes of gases contain equal numbers of molecules.
- Gay-Lussac's law of combining volumes: Under conditions of constant temperature and pressure, the ratios of the volumes of gases that react are small whole numbers.
- Dalton's law of partial pressures: the total pressure of a mixture of gases is equal to the sum of the partial pressures of each component of gas.
- Charles' law: The volume of a gas is directly proportional to its absolute temperature if the pressure remains constant.
- Combined gas law: the pressure, volume, and temperature of a gas are all related if the quantity of gas remains constant.
- Kinetic Energy: energy of motion
- Potential Energy: energy of position
- Diffusion: gradual mixing of two gases due to spontaneous, random motion
- Brownian Motion: random movement of microscopic particles resulting from collisions with molecules
- Elastic: collision in which particles do not lose energy
- Heat: total kinetic energy of all the molecules of a substance
- SI unit of measure- Joule
ment of heat - Temperature: average kinetic energy of the molecules of a substance
- Heat capacity: amount of heat required to raise the temperature of a substance 1 degree
- Specific Heat: amount of heat required to raise the temperature of 1.0 gram of a substance 1 degree celsius
- Heat of Fusion: additional heat required to melt a substance at its melting point
- Heat of Vaporization: additional energy required to vaporize a substance at its boiling point
- Equilibrium Vapor Pressure: pressure of a gas in re a state of equilibrium with its liquid
- Pascal: SI unit of measurement for pressure
- Cohesion: molecular force of attraction for other molecules within the same substance
- Meniscus: concave depression on the surface of a liquid
- Viscosity: ability of a liquid to resist flowing
- Crystal: a solid consisting of particles arranged in an orderly, repeating, geometric pattern
- X-Ray Diffraction: process used to examine the crystal structure of a solid
- Allotrope: one of the different forms of a polymorphous crystalline solid
- Amorphous: a type of solid in which the particles have no crystal structure
- Polymorphous: a type of solid in which the particles occur in more than one crystal pattern
- Capillarity: movement of a liquid up or down a tube because of adhesion
- Adhesion: attraction between molecules of two substances in contact with each other
- Effusion: gradual escape of a gas through a small opening in its container
- gay lusaac's law: P/T=K
- combined gas law: PV/T=K
- avogadro's principle: V=kn
- ideal gas law: PV=nRT
- Pt: pt=p1+p2+p3: dalton's law of partial pressures
- Ra/Rb = Mb/M: graham's law of effusion/diffusion
- charles' law: V/T=k
- boyle's law: PV=k
- How do gas molecules move?: rapidly, randomly, and constantly in straight-line paths in any direction
- equilibrium: exists when two opposing chemical or physical changes occur at equal rates in a closed system.
- Surface tension: the property of a liquid that makes the surface of a liquid flat and pulls a droplet into a sphere.
- Viscosity, which is affected by temperature is caused bycohesive forces within a liquid.
- The pattern of a crystal is caused by the attraction and repulsion of electrically charged particles within the crystal.
- The Kelvin Scale represents the absolute temperature and its degrees are always expressed as positive numbers
