Temperature has a big effect on how fast things spread out or diffuse in our cells. When the temperature goes up, the tiny particles, or molecules, in our body move around more quickly. This means diffusion happens faster too.

How Temperature Affects Diffusion:

1. Faster Movement of Molecules: When it gets hotter, molecules move faster. For example, if the temperature goes up by 10 degrees Celsius, the rate of diffusion can double!

2. Diffusion Coefficient: There’s a way to show how temperature affects diffusion using a simple formula:
   $D = \frac{kT}{b}$
   Here, $D$ is the diffusion coefficient, $k$ is a tiny number called Boltzmann's constant, $T$ is the temperature measured in Kelvin, and $b$ is a constant that depends on the environment.

3. Importance for Living Cells: For our human cells, diffusion is really important because it helps move oxygen and nutrients. This is key for processes like breathing and using energy. The best temperature for these processes is around 37 degrees Celsius, showing us how important it is to keep our body temperature just right.

Knowing how temperature affects diffusion is really important in areas like medicine and biology. Changes in temperature can change how medicines work and how our body uses energy.
