Which law states that the volume of a given amount of gas held at constant pressure is directly proportional to the Kelvin temperature?
Correct answer: C. Charles' Law
- A. Graham's Law
- B. Avogadro's Law
- C. Charles' Law
- D. Boyle's law
Explanation
Charles’ law links volume and absolute temperature at constant pressure: heating a gas increases its volume in direct proportion to its Kelvin temperature. Temperature must be expressed in Kelvin, not Celsius.
