plinovi

Plinovi is the plural form of the noun plin in several South Slavic languages, meaning gases. In scientific usage, plinovi refer to substances that exist primarily in the gaseous state under ordinary conditions. Gases have no fixed shape or volume; they expand to fill their container, are highly compressible, and consist of rapidly moving particles. Their macroscopic behavior is commonly described by the ideal gas law, PV=nRT, with real-gas corrections at high pressures or low temperatures.

Gases can be broadly classified as simple (monoatomic like helium, neon, argon) or diatomic and polyatomic (nitrogen, oxygen, carbon dioxide, methane, ammonia, sulfur hexafluoride). Some gases act as greenhouse gases in the atmosphere, including carbon dioxide, methane, nitrous oxide, and halogenated compounds. Others are produced and used industrially or medically, such as oxygen for respiration, nitrogen for inert atmospheres, hydrogen for synthesis, and chlorine for chemical processing. Air is a natural mixture of mainly nitrogen and oxygen and serves as a typical ambient gas.

Applications of plinovi span science, industry, medicine, and environmental management. They include respiration support, welding and metal fabrication with shielding gases, cryogenics with liquid nitrogen, process control, and packaging technologies. Safety concerns center on toxicity, flammability, corrosivity, and asphyxiation risks; many plinovi require proper containment, ventilation, leak detection, and compliance with handling regulations.

In everyday usage, plinovi can refer to gases in general or to specific gas fuels such as natural gas, depending on context.
