Question 112

Two otherwise identical diffusion setups differ only in temperature. Which setup will generally show faster diffusion?

  1. The cooler setup, because particles move more slowly
  2. The warmer setup, because particles move fasterCorrect answer
  3. Both must have zero diffusion at different temperatures
  4. Temperature cannot affect particle motion

Explanation

At the higher temperature, particles have greater average kinetic energy and move faster, so diffusion generally proceeds more rapidly. Choosing the cooler setup would wrongly associate slower particle motion with a higher diffusion rate.
