How do cold gases diffuse compared to hot gases?

Hot gases diffuse more quickly than cold gases due to their higher energy levels. In a gas, the molecules are in constant motion, and this motion is influenced by temperature. Hot gases, having greater thermal energy, exhibit increased molecular motion, resulting in more frequent and energetic collisions between molecules. This leads to a faster rate of diffusion as the molecules spread out more readily in the surrounding space.

Cold gases, on the other hand, have lower energy levels, which mean that their molecules move more slowly. This reduced motion results in fewer collisions and a slower rate of spreading out in comparison to their hot counterparts. Therefore, when comparing the diffusion rates between cold and hot gases, the clear distinction is that cold gases diffuse slowly, while hot gases do so more quickly.
