Key Concepts

Gas Laws

• Gas laws are principles that describe the behavior of gases in various conditions.

Combined Gas Law

• Describes the relationship between pressure, volume, and temperature of a gas.

Pressure

• Pressure is the force exerted by particles against the walls of its container.

Atmospheric Pressure

• Atmospheric pressure is the force exerted by the weight of the atmosphere.

Standard Temperature and Pressure (STP)

• Standard Temperature and Pressure are conditions (0°C and 1 atm) used to measure gas properties.

Ideal Gas Law

• Relates pressure, volume, temperature, and moles of a gas: ( PV = nRT ).

Density of Gases

• Density is defined as mass per unit volume.

Molar Mass of Gases

• Molar mass is the mass of a given substance (chemical element or chemical compound) divided by its amount of substance.
