## Combined Gas Laws (Pressure-Volume-Temperature Relationship for a Gas) or The Equation of State

Combined Gas Laws: To arrive at a combined relationship between pressure, volume and temperature of a given mass of a gas, Boyle’s and Charle’s law are combined into one equation. The equation so obtained is called the Gas Equation or the Equation of State. Let P1, V1, T1 be the original (initial) pressure, volume and temperature …
