How is Charles's Law defined?

Charles's Law is defined as the principle that describes the relationship between the volume of a gas and its absolute temperature when pressure is held constant. Specifically, it states that the volume of a gas is directly proportional to its absolute temperature (measured in Kelvin). This relationship means that if the temperature of a gas increases, the volume will also increase, provided the pressure does not change.

This direct proportionality can be mathematically expressed as V ∝ T, or rearranged to V/T = k, where V is volume, T is temperature, and k is a constant. This law helps explain behavior under varying temperature conditions, reflecting the kinetic theory of gases, which suggests that gas particles move more vigorously at higher temperatures, resulting in greater volume occupancy.

The other statements do not accurately represent Charles's Law. For instance, one option speaks of inverse proportionality to pressure, which relates to Boyle’s Law rather than Charles’s Law. Another option suggests a constant volume regardless of temperature changes, which contradicts the very essence of the law. Lastly, the idea that all gases occupy the same volume at a specific temperature is not a characteristic of Charles's Law; instead, it relates more broadly to the behavior of gases under the ideal gas law.
