A gas pycnometer is a laboratory device used for measuring the density—or, more accurately, the volume—of solids, be they regularly shaped, porous or non-porous, monolithic, powdered, granular or in some way comminuted, employing some method of gas displacement and the volume:pressure relationship known as Boyle's law.
Boyle's law demonstrations. The law itself can be stated as follows: For a fixed mass of an ideal gas kept at a fixed temperature, pressure and volume are inversely proportional. [2] Boyle's law is a gas law, stating that the pressure and volume of a gas have an inverse relationship. If volume increases, then pressure decreases and vice versa ...
The laws describing the behaviour of gases under fixed pressure, volume, amount of gas, and absolute temperature conditions are called gas laws.The basic gas laws were discovered by the end of the 18th century when scientists found out that relationships between pressure, volume and temperature of a sample of gas could be obtained which would hold to approximation for all gases.
The second of these essays (De la nature de l'air) contains the statement of the law that the volume of a gas varies inversely as the pressure. [10] [11] It was made from the discovery by Robert Boyle in 1662; Mariotte said Boyle's theory was right only when the temperature is constant. However, outside France it is best known as Boyle's law. [12]

Boyle's law states that at a constant temperature, volume (V) and pressure (P) are inversely related. Therefore, when a constant temperature is maintained (isothermal conditions), Boyle's law can be applied. Consequently, most early plethysmographs required temperature-controlled surroundings and isothermal conditions within the test chamber. [1]

An example of the use of idealization in physics is in Boyle's Gas Law: Given any x and any y, if all the molecules in y are perfectly elastic and spherical, possess equal masses and volumes, have negligible size, and exert no forces on one another except during collisions, then if x is a gas and y is a given mass of x which is trapped in a vessel of variable size and the temperature of y is ...
