Question

1.)what is the effect of temperature on the rate of diffusion?

2.) Arrange the following substances in the increasing order of force of attraction between their particles
oxygen,salt,milk​

Answer 1

Answer:

when the temperature is increase the rate of diffusion also increase because due to increase in temperature the kinetic energy of the particles increases therefore the diffusion particle will move with greater speed so the the rate of diffusion will increase

Salt is a solid milk is a liquid oxygen is gas and we conclude that the solid particles have maximum force of attraction whereas the gases particles have least force of attraction and the liquid particle have intermediate force of attraction between gases and solid there for the increasing order of force of attraction between the particles will be

Oxygen <Milk <Salt

Answer 2

Answer:

1)Temperature: Higher temperatures increase the energy and therefore the movement of the molecules, increasing the rate of diffusion. Lower temperatures decrease the energy of the molecules, thus decreasing the rate of diffusion. Solvent density: As the density of a solvent increases, the rate of diffusion decreases.

2)The correct answer is oxygen, milk and salt. The first substance in the list is a gas therefore its molecules are bounded by loose forces of attraction. In fact, you can find sufficient inter molecular space. Milk is a liquid with forces of attractions between the molecules considerably higher than gas.
