Which gas law states that the volume of a gas is directly proportional to its temperature at constant pressure?
Correct Answer: Charles's Law
- Step 1: Understand that gases can change their volume when temperature changes.
- Step 2: Remember that 'directly proportional' means that when one thing increases, the other also increases.
- Step 3: Know that this relationship happens when the pressure of the gas stays the same.
- Step 4: Identify that the specific gas law that describes this relationship is called Charles's Law.
