Boyle's law of the gas, and "k" is a constant. The equation states that the product of pressure and volume is a constant for a given mass of confined gas and this holds as long as the temperature is constant. For comparing the same substance under two different sets of conditions, the law can be usefully expressed as The equation shows that, as volume increases, the pressure of the gas decreases in proportion. Similarly, as volume decreases, the pressure of the gas increases. The law was named after chemist and physicist Robert Boyle, who published the original law in 1662. This relationship
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
