GAS LAWS

There are some relationships among temperature, volume, pressure, and quantity of a gas that could be described mathematically. This chapter deals with Boyle’s law, Charles’s law, Gay–Lussac’s law, and the combined gas law. These laws have one condition in common, i.e., fixed mass. In addition, some other properties of gases such as internal energy, specific heat capacity, and enthalpy have been introduced. Some of the important non-flow processes such as constant volume process, constant pressure process, isothermal processes, polytropic process, and adiabatic process have been explained with suitable examples. Some laws have been proposed by the various chemists such as Boyle’s law, Charle’s law, Gay–Lussac’s law based on the behaviour of ideal gases. These laws are discussed in the following subsections.
