ideal gas law

The ideal gas law is a fundamental equation in chemistry that describes the behavior of gases. It combines four key variables: pressure (how hard gas particles hit surfaces), volume (the space the gas occupies), temperature (how hot the gas is), and the number of particles (amount of gas). The law states that, under certain conditions, the relationship among these variables can be expressed as PV = nRT, where P is pressure, V is volume, n is the number of moles of gas, R is the gas constant, and T is temperature in Kelvin. This helps predict how gases will behave in various situations.
