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.
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, when the temperature is held constant.
Isotherms of an ideal gas for different temperatures. The curved lines are rectangular hyperbolae of the form y = a/x. They represent the relationship between pressure (on the vertical axis) and volume (on the horizontal axis) for an ideal gas at different temperatures: lines that are farther away from the origin (that is, lines that are nearer to the top right-hand corner of the diagram ...

V is the volume of the gas, T is the temperature of the gas (measured in kelvins), and; k is a constant for a particular pressure and amount of gas. This law describes how a gas expands as the temperature increases; conversely, a decrease in temperature will lead to a decrease in volume.
In 1968, Anderson developed (∂T/∂P) v =(αK) −1 for the thermal gradient, [7] and its reciprocal correlate the thermal pressure and temperature in a constant volume heating process by (∂P/∂T) v =αK. [8] Note, thermal pressure is the pressure change in a constant volume heating process, and expressed by integration of αK.
V is the volume of the gas; n is the amount of substance of the gas (measured in moles); k is a constant for a given temperature and pressure. This law describes how, under the same condition of temperature and pressure, equal volumes of all gases contain the same number of molecules. For comparing the same substance under two different sets of ...
