3.1 Volume-Temperature Relationship
The core of Charles’s Law is the direct proportionality between a gas’s volume and its temperature in Kelvin, at constant pressure. This relationship means that as temperature increases, volume also increases proportionally, and vice versa. For example, if the temperature of a gas doubles (in Kelvin), its volume also doubles, provided pressure remains unchanged.
