Charles’ law is an experimental gas law which describes how gases tend to expand when heated. When the pressure on a sample of a dry gas is held ... more
The ideal gas law is the equation of state of a hypothetical ideal gas. It is a good approximation to the behaviour of many gases under many conditions, ... more
Planck temperature, denoted by TP, is the unit of temperature in the system of natural units known as Planck units.
It serves as the ... more
In chemical kinetics, the pre-exponential factor or A factor is the pre-exponential constant in the Arrhenius equation. Here named as Arrhenius number.
