Partial Pressure of Gases

Partial Pressures of Gases

The pressures exerted by individual gases in a mixture.

Ideal Gas Law

A mathematical relationship between the pressure, volume, temperature, and number of moles of a gas.

Total Pressure

The sum of the partial pressures of all the gases in a mixture.

Volume

The amount of space occupied by a gas.

Temperature

A measure of the average kinetic energy of gas particles.

Oxygen Gas

A diatomic molecule (O2) that is essential for many chemical reactions and respiration.

Nitrogen Gas

A diatomic molecule (N2) that makes up the majority of Earth's atmosphere.

Ideal Gaseous Mixture

A mixture of gases that behaves according to the ideal gas law.

Partial Pressure of Gas Z

The pressure exerted by a specific gas component in a mixture after the addition of Gas Z.

Complete Combustion

A combustion reaction where a fuel is burned completely, producing only carbon dioxide and water.

Moles of Oxygen

The amount of oxygen molecules needed for a complete combustion reaction.

Jar Volume

The amount of space needed in a jar to hold enough oxygen for a complete combustion reaction.

Collecting Gases over Water

A method of collecting gases by displacing water in a container.

Partial gas pressures

The individual pressures exerted by each gas in a mixture.

Vapor pressure

The pressure exerted by the vapor of a substance in equilibrium with its liquid phase.

Partial pressure

The pressure exerted by a single gas in a mixture.

Dalton's law

The law stating that the total pressure of a gas mixture is equal to the sum of the partial pressures of each gas in the mixture.

Mole fraction

The ratio of the number of moles of a component to the total number of moles in a mixture.

Total pressure

The sum of the partial pressures of each gas in a mixture.

Mole

A unit of measurement used to quantify the amount of a substance.
