Explanation

Ideal gas law: PV = nRT (n = moles, R = 8.31 J/mol·K). Combined gas law: P₁V₁/T₁ = P₂V₂/T₂. Temperature must be in Kelvin (K = °C + 273).

At constant T: PV = constant (Boyle). At constant P: V/T = constant (Charles). At constant V: P/T = constant (Pressure law).

Real gases deviate from ideal behavior at high pressure and low temperature. Ideal gas assumptions: negligible particle volume, no intermolecular forces, elastic collisions.
