gas butane canister

Gas Butane Canister is both a gas AND a liquid, depending entirely on its temperature and pressure. Understanding this duality is key to safely and effectively using everything from pocket lighters to camping stoves and industrial applications.  The Core Science: Phase Changes & Vapor Pressure Butane (C₄H₁₀) is a hydrocarbon gas at standard room temperature (around 20°C or 68°F) and atmospheric pressure. However, unlike gases that are difficult to liquefy (like hydrogen or helium), butane has a relatively low boiling point of approximately -0.5°C (31.1°F) at sea level pressure. This low boiling point is crucial: Gaseous State: At room temperature and normal atmospheric pressure, butane exists as a colorless, odorless gas.  Liquefied State: […]
