Questions & Step-by-Step Solutions

If the temperature of a gas is increased from 300 K to 600 K, how does the RMS speed change?
  • Step 1: Understand that RMS speed (Root Mean Square speed) of a gas is related to its temperature.
  • Step 2: Know the formula that relates RMS speed (v_rms) to temperature (T): v_rms is proportional to the square root of T.
  • Step 3: Identify the initial temperature (T1) as 300 K and the final temperature (T2) as 600 K.
  • Step 4: Calculate the ratio of the final temperature to the initial temperature: T2 / T1 = 600 K / 300 K = 2.
  • Step 5: Find the square root of this ratio: sqrt(2).
  • Step 6: Conclude that the RMS speed increases by a factor of sqrt(2) when the temperature increases from 300 K to 600 K.
