  1. Question 1

    Q1. A gas expands isothermally from 2 L to 4 L. If the initial pressure is 2 atm, what is the final pressure?

    • A) 1 atm
    • B) 2 atm
    • C) 0.5 atm
    • D) 4 atm

    Answer: 1 atm

    Explanation: Boyle's Law: P1V1 = P2V2, so P2 = 1 atm. Option B is initial pressure, not final.
