According to Boyle's law, at a constant temperature, the volume of a given mass of a gas is inversely proportional to its pressure. p ∝ 1 V at constant temperature Charle's law states that the volume of an ideal gas is directly proportional to the absolute temperature at constant pressure. V ∝ T Dalton’s law: At constant V and T , total pressure of the gaseous mixture of two or more non reacting gases is equal to the algebraic sum of their partial pressures. p Total = p 1 + p 2 + p 3 + . . . . . . at constant temperature and volume Avogadro law: It states that equal volumes of all gases, under the same conditions of temperature and pressure, contain equal number of molecules.

According to Boyle's law, at a constant temperature, the volume of a given mass of a gas is inversely proportional to its pressure. Since the temperature is constant, the graph is called isotherm. According to Boyle's law, at a constant temperature, pressure of the gas is directly proportional to 1 / V . So straight line is formed from the origin. According to Boyle's law, at a constant temperature, product of pressure and volume is always constant. PV = constant. (b) p vs . V (c) p vs . 1 V (a) pV vs . V
