States that equal volumes of gases at the same temperature and pressure contain an equal number of particles
Avogadros law
States that equal volumes of gases at the same temperature and pressure contain an equal number of particles. Avogadro's law. It means that if you have two balloons of the same size at the same temperature and pressure, they contain the same number of gas molecules.

States that pressure increases when volume decreases, and vice versa , if the gas temperature is constant
Boyles law
States that pressure increases when volume decreases, and vice versa, if the gas temperature is constant. Boyle's Law It describes how gas pressure and volume are inversely related at constant temperature.

States that when gas pressure is constant, its volume increases with temperature, gases expand when heated
Charles law
States that when gas pressure is constant, its volume increases with temperature, gases expand when heated. Charles's Law. It explains how increasing the temperature of a gas causes it to expand if the pressure remains unchanged.

Describes the relationship between pressure, temperature and volume of an enclosed gas
Combined gas law
Describes the relationship between pressure, temperature and volume of an enclosed gas. Combined gas law. It shows how these three properties of a gas change together when conditions change, keeping the amount of gas constant.

The total pressure of a mixture of gases equals the sum of the pressures of all the gases
Daltons law of partial pressures
The total pressure of a mixture of gases equals the sum of the pressures of all the gases. Dalton's law of partial pressures. Dalton's law states that in a mixture of gases, each gas contributes to the total pressure independently of the others.

The pressure of a gas is directly proportional to the Kelvin temperature if the volume remains constant
Gay Lussacs law
The pressure of a gas is directly proportional to the Kelvin temperature if the volume remains constant. Gay Lussac's law. In simple terms, Gay Lussac's law explains that if you heat a gas inside a sealed container, its pressure will increase.

The rate of effusion of a gas is inversely proportional to the square root of its molar mass
Grahams law of effusion
The rate of effusion of a gas is inversely proportional to the square root of its molar mass. Graham's law of effusion states that lighter gases escape through a tiny opening faster than heavier gases.

A theoretical gas whose particles are infinitely small and do not interact with each other
Ideal gas
A theoretical gas whose particles are infinitely small and do not interact with each other. Ideal gas. An ideal gas is a simplified model that helps scientists understand and calculate the behavior of real gases under certain conditions.

A constant used in the ideal gas law, its value depends on the units used
Ideal gas constant
A constant used in the ideal gas law, its value depends on the units used. Ideal gas constant. The ideal gas constant is a number that relates the energy of gas particles with temperature and pressure in calculations.

The relationship between pressure (P), volume (V), and temperature (T) of an ideal gas. PV=nRT
Ideal gas law
The relationship between pressure P, volume V, and temperature T of an ideal gas PVnRT. Ideal gas law. The ideal gas law is a formula that describes how the pressure, volume, and temperature of a gas are related, assuming the gas behaves perfectly.
