Gas Laws Flashcards

Vocabulary flashcards for gas laws review.

Diffusion

Tendency for molecules to move toward lower concentration until concentration is uniform.

Effusion

Gas escapes through a tiny hole.

Diffusion and Effusion

Gases of lower molar mass diffuse and effuse faster than gases of higher molar mass.

Ideal gases:

Have no volume (insignificant amount), Have neither adhesive or cohesive properties

Real gases

Have volume, have attractions to other molecules

Partial pressure

Each gas in the mixture has its own pressure.

Dalton’s Law of Partial pressure

Relates the pressures of gases in a mixture. Ptotal = P1 + P2 + P3…… Pn

Gay-Lussac's Law

As temperature increases, the pressure increases if volume is constant.

Charles's Law

As temperature increases, volume increases if the pressure is constant

Boyle's Law

If temperature is constant then as pressure increases then volume decreases

Kinetic Molecular Theory

Particles in a gas are small, hard spheres with insignificant volume; Gas Particles are in constant motion; Collisions between gas particles are perfectly elastic
