Chemistry Chapter 11 Voicab

Describes the behavior of gases in terms of particles in motion; makes several assumptions about size, motion, and energy of gas particles.

• Kinetic Molecular Theory

• Dalton's Law of Partial Pressure

• hydrogen bond

• surfactant

Collision in which no kinetic energy is lost; kinetic energy can be transferred between the colliding particles, but the total kinetic energy of the two particles remains the same. 

• elastic collision

• dipole-dipole forces

• surfactant

• allotrope

A measure of the average kinetic energy of the particles in a sample of matter.

• temperature

• pressure

• viscosity

• diffusion

The movement of one material through another from an area of higher concentration to an area of lower concentration.

• diffusion

• pressure

• temperature

• surface tension

States that the rate of effusion for a gas is inversely proportional to the square root of its molar mass.

• Grahm's Law of effusion

• Kinetic-Molecular theory

• unit cell

• triple point

Force applied per unit area.

• pressure

• surface tension

• dispersion force

• hydrogen bond

An instrument that is used to measure atmospheric pressure.

• barometer

• unit cell

• crystalline solid

• allotrope

The SI unit of pressure; one pascal (Pa) is equal to a force of one newton per square meter. 

• pascal

• unit cell

• surfactant

• atmosphere

The unit is often used to report air pressure.

• atmosphere

• pascal

• unit cell

• allotrope

States that the total pressure of a mixture of gases is equal to the sum of the pressures of all the gases in the mixture.

• Dalton's Law of Partial Pressures

• Kinetic-Molecular Theory

• allotrope

• dipole-dipole forces
