What is Ideal Gas Law?
The equation of state for an ideal gas: PV = nRT, where P is pressure, V is volume, n is moles, R is the gas constant (8.314 J/mol·K), and T is absolute temperature. Real gases approximate ideal behavior at low pressures and high temperatures.

High-pressure gas cylinders are explosion hazards if overheated or damaged. Compressed flammable gases (H₂, CH₄) are fire/explosion risks. Toxic gases (CO, Cl₂, H₂S) require gas detectors, ventilation, and respiratory protection. Always secure gas cylinders upright and away from heat sources. Check …
