Charles's law states that the volume of a gas is directly proportional to its temperature when pressure and the amount of gas are held constant. Mathematically, it is expressed as $V \propto T$ or $\frac{V_1}{T_1} = \frac{V_2}{T_2}$.
5 Must Know Facts For Your Next Test
Charles's law requires temperature to be in Kelvin for accurate calculations.
The relationship described by Charles's law means that if the temperature of a gas increases, its volume increases proportionally.
Charles's law can be derived from the Ideal Gas Law by holding pressure and amount (moles) constant.
Real gases follow Charles's law closely at high temperatures and low pressures.
Graphically, Charles's law is represented as a straight line when plotting volume against temperature.
