Question

What is the effect of the following in the rate of diffusion-
1 ) Temperature
2) Density of liquid
answer fast please​ , it's urgent please

Answer 1

Answer:

(a)Rate of diffusion increases with increase in temperature due to increase in the kinetic energy of the particles

(b) On increasing the temperature, the diffusion increases and on increasing the density of substance, the diffusion decreases and vice versa. As the density of the liquid increases rate of diffusion will be decreases.

Explanation:

I hope it's helpful ☺️

Answer 2

ANSWER:

At high temperature, the kinetic energy of gas molecules increases as a result the collision between the molecules increases. Therefore, the molecules will spread more quickly. Hence, on increasing the temperature, the rate of diffusion also increases. Whereas density is the mass per unit volume
