Why plastic do not rust

it can't rust simply because it doesn't contain any iron or any of it's alloys. In fact, not even all metals rust.

Explanation:

answer: the rate of diffusion increases with increase in temperature.

increase in temperature, increases the molecular/particles speed (kinetic energy. diffusion means movement of particles through the material.

generally, the heavier the particle the more it interacts with the environment and more the temperature matters. so higher temperature results in higher diffusion.
