How does temperature affect diffusion of gaseous substances?

Diffusion is faster at higher temperatures because the gas molecules have greater kinetic energy, because of that, they move faster.

Describe Solute, solvent and Solution? With examples.

solutes can be liquids or solids. Solvents are always liquids. So solution is when you mix a solute and a solvent.

Describe and state their charges and mass for: NEUTRONS

NEUTRONS have no electric charge and their mass is very close to the one from the proton, which by our needs can just be considered the same, 1u.
