  1. Question 1

    Q1. The root mean square speed of the molecules of a gas is given by the equation:

    • A) √(3RT / M)
    • B) √(2RT / M)
    • C) √(RT / M)
    • D) √(3R / MT)

    Answer: √(3RT / M)

    Explanation: The RMS speed = √(3RT / M), where R is the gas constant, T is temperature, and M is molecular weight.
