What is absolute zero, and why is it the lowest possible temperature?
Original Khojo Papers practice question — not from a past board paper.
Answer
Absolute zero is −273 °C, the temperature at which the volume of an ideal gas would become zero if Charles' law continued to hold. It is the lowest possible temperature because the kinetic energy of the molecules would be at its minimum there, and no lower temperature can be defined.
No citable source has been recorded for this record. Treat it as practice material, not as fact.
Explanation
In practice a real gas liquefies long before it is reached.
