Answer: States of matter; increases
Several factors influence the rate of diffusion and among these factors are temperature, STATES OF MATTER, electrical currents, and molecular size. For example, as temperature INCREASES, the rate of diffusion increases.
Explanation:
Factors influencing the rate of diffusion include:
- Temperature: High temperature increases the speed at which molecules move. Thus, as temperature increases, the rate of diffusion increases
- States of matter: Diffusion varies within the three states of matter. The diffusion of gases is much faster than that of liquids and solids, because the gas molecules are freer and therefore faster than the rest.
- Molecular size: The smaller the molecules, the faster the rate of diffusion while the larger the molecules, the slower the rate of diffusion.
Other factors include electrical currents.

Explanation:
The phanerozoic geologic era is divided into three and the paleozoic era is the first among them. The paleozoic era occurred about 902 million years ago and it divided into six different periods. It was a time of dramatic changes in term of climate, geology and evolution.
During the first period of the paleozoic era large number of creatures evolved, this is called Cambrian explosion. Most of the biological classes that are still prevalent today such as primitive fish and coral were evolved during this era. Mass evolution of fish also occured during this era. <span />
