Explanation of the ideal gas law, including its formula and how it relates to temperature, pressure, and volume.
The ideal gas law (PV = nRT) relates the macroscopic properties of ideal gases. An ideal gas is a gas in which the particles (a) do not attract or repel one another and (b) take up no space (have no volume).

Discover how the Italian chemist Amedeo Avogadro's experiments with tiny particles led to the postulation that equal volumes of gas at the same temperature and pressure contain equal number of particles. This fundamental principle forms the basis of the ideal gas equation, a cornerstone in the study of physical processes.

For a mixture of ideal gases, the total pressure exerted by the mixture equals the sum of the pressures that each gas would exert on its own. This observation, known as Dalton's law of partial pressures, can be written as follows: P (total) = P ₁ + P ₂ + P ₃ + ... where P ₁, P ₂, and P ₃ are the partial pressures of the different ...
