    Q1. Which gas’s liquid form has the lowest surface tension compared to other common liquid gases?

    • A) NH3
    • B) CH4
    • C) CO2
    • D) H2O

    Answer: CH4

    Explanation: CH4’s weak van der Waals forces reduce surface tension. NH3 has hydrogen bonding, increasing surface tension.
