Ineed with questions 29,31,34,38 and it’s very hard and i’m struggling with it and if you need to see the picture big then click on it and it will be big

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.
