  1. Question 1

    Q1. A scuba diver surfaces rapidly. What process occurs in their air-filled spaces, leading to a decrease in gas pressure?

    • A) Expansion due to increased temperature
    • B) Compression due to increased temperature
    • C) Expansion due to increased pressure
    • D) Compression due to decreased pressure

    Answer: Compression due to decreased pressure

    Explanation: Rapid ascent results in decreased ambient pressure, causing expansion of gases in air-filled spaces, not expansion due to temperature changes.
