السؤال 112

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

The cooler setup, because particles move more slowly
The warmer setup, because particles move fasterالإجابة الصحيحة
Both must have zero diffusion at different temperatures
Temperature cannot affect particle motion

الشرح

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.
