Gas laws 1662 Robert Boyle studied the relationship between volume and pressure of a gas of fixed amount at constant temperature. He observed that volume of a given mass of a gas is inversely proportional to its pressure at a constant temperature. Boyle's law, published in 1662, states that, at constant temperature, the product of the pressure and volume of a given mass of an ideal gas in a closed system is always constant. It can be verified experimentally using a pressure gauge and a variable volume container. It can also be derived from the kinetic theory of gases: if a container,
Volume (thermodynamics) without reference to an exact operating volume, which may not be known (nor significant) at some stages of analysis. The specific volume of a substance is equal to the reciprocal of its mass density. Specific volume may be expressed in formula_14, formula_15, formula_16, or formula_17 . where, formula_3 is the volume, formula_20 is the mass and formula_21 is the density of the material. For an ideal gas, where, formula_23 is the specific gas constant, formula_24 is the temperature and formula_25 is the pressure of the gas. Specific volume may also refer to molar volume. The volume of gas increases proportionally
