FAQs
Why must temperature be in Kelvin for Charles's Law?
Because the relationship requires absolute temperature. At absolute zero (0 K = -273.15°C), gas volume would theoretically reach zero. Using Celsius gives incorrect results because 0°C is not absolute zero — it is an arbitrary point on the Celsius scale.
How does Charles's Law explain hot air balloons?
Heating the air inside a balloon increases its volume (at constant atmospheric pressure), making it less dense than the surrounding cooler air. The buoyancy force exceeds the weight of the balloon and occupants, causing it to rise. Cooling the air causes the balloon to descend.
What is the combined gas law?
The combined gas law merges Boyle's Law (pressure-volume) and Charles's Law (volume-temperature) into: P₁V₁/T₁ = P₂V₂/T₂. This allows simultaneous changes in all three variables while the amount of gas remains constant.
