Gázkeverékeknél refers to situations involving gas mixtures in scientific and engineering contexts. A gas mixture is a homogeneous combination of two or more gases. The properties of a gas mixture are generally determined by the properties of its individual components and their proportions.

In thermodynamics and physical chemistry, the behavior of gas mixtures is often described using ideal gas laws or more complex equations of state that account for intermolecular forces and molecular volume. Dalton's Law of Partial Pressures states that the total pressure exerted by a mixture of non-reacting gases is equal to the sum of the partial pressures that each individual gas would exert if it occupied the same volume alone. Amagat's Law of Partial Volumes describes the total volume of a gas mixture as the sum of the partial volumes of each component gas at the same temperature and pressure.

Gas mixtures are ubiquitous in nature and industry. The Earth's atmosphere is a prime example, composed primarily of nitrogen and oxygen, with smaller amounts of argon, carbon dioxide, and trace gases. Industrial processes frequently utilize gas mixtures, such as in combustion, welding, and chemical synthesis. For instance, propane and butane are mixed to create liquefied petroleum gas (LPG), a common fuel. The study of gas mixtures is crucial for understanding chemical reactions, designing engines, and ensuring safe handling of various gases.
