Why must the temperature be converted to the kelvin scale in gas law calculations?
Original Khojo Papers practice question — not from a past board paper.
Answer
The gas laws relate volume and pressure to absolute temperature, measured from absolute zero, where the volume of an ideal gas would be zero. The Celsius scale has an arbitrary zero at the melting point of ice, so ratios of Celsius temperatures are meaningless and can even be negative.
No citable source has been recorded for this record. Treat it as practice material, not as fact.
Explanation
The conversion is K = °C + 273.
