State Boyle's law and Charles' law.
Original Khojo Papers practice question — not from a past board paper.
Answer
Boyle's law states that at constant temperature the volume of a fixed mass of gas is inversely proportional to its pressure. Charles' law states that at constant pressure the volume of a fixed mass of gas is directly proportional to its absolute temperature.
No citable source has been recorded for this record. Treat it as practice material, not as fact.
Explanation
Both hold only for a fixed mass of gas.
