Answers
Answer:
hey mate your answers r here
Explanation:
3) solid are tightly packed liquid are not tightly packed as much as the solids and gases have greater intermolecular space
solids r tightly packed ,liquids have little intermolecular forces of attraction andgases have very less intermolecular force of attraction
4)because copper sulphate is of blue colour when dissolved in the water the water becomes blue hi
5) gases diffuse very fast because they have a higher kinetic energy
6) matter is made up of solid ,liquid and gas and so matter exerts pressure and therefore gas also exerts pressure
7) matter is made up of small particles known as atoms and molecules
the the three States of matter are solid liquid and gas.
8) in osmosis only solute can pass semipermeable membrane but in diffusion solute and solvent both can pass through it.
