GAY-LUSSAC’S LAW: Temperature-Pressure
relationship
“The pressure of a fixed amount of a gas is directly
proportional to the absolute temperature (Kelvin).”
One of the postulates of the Kinetic Molecular Theory
is the effect of temperature on the motion of gas
particles. The pressure of a gas increased or decreased
proportionally with a change in temperature. It can be
mathematically expressed as follows:
P= kT or
