Question

what is the effect of the following on the rate of diffusion ? (i) temprature (ii) density of liquid

Answer 1

i) Temperature
Effect: The molecules will have more kinetic energy for faster diffusion across a membrane or in the air/liquid.

ii) Density of liquid
Effect: If the liquid molecules are dense, it is harder for them to diffuse as they are heavy. If the density is light, it allows easier diffusion of the molecules.
