Charles's Law states that at a constant pressure, the volume of a gas increases or decreases in direct proportion to its temperature measured in Kelvin. Essentially, if you heat a gas, it will expand, and if you cool it, it will contract, provided pressure remains unchanged. This relationship helps explain why a hot air balloon rises when the air inside heats up and why gases behave predictably under temperature changes, making it fundamental in understanding gas behavior in various scientific and practical contexts.
