  1. Question 1

    Q1. The temperature of an ideal gas is increased from 27°C to 327°C. The rms speed of the gas molecules will increase by a factor of

    • A) √2
    • B) 2
    • C) √10
    • D) 4

    Answer: √10

    Explanation: v_rms ∝ √T, so the ratio of v_rms at 600K and 300K is √(600/300) = √2, hence the factor is √2, but considering the options and the actual calculation: √(600/300) = √2.
