Question

How does the rate of diffusion change with - density of liquid temperature?

Answer 1

#Rate of diffusion in terms of density:
Density means the space between inter-molecular space(tightly or lightly packed). So when density is more means molecular spaces is small. Therefore any substance is to be dissolved in it is difficult.
But, when density is less means molecular spaces is larger then any substance is to be dissolved in it is easy.

#Rate of diffusion in terms of temperature:
If temperature is less then it means molecular is less. So, any substance is to be dissolved in it, it is difficult.
But, if temperature is more then it means molecular space is more. So, any substance is to be dissolved in it, it is easy.

Answer 2

Explanation:

Ever notice that when you pour a darker liquid into clear water the overall color changes into a shade between both? Diffusion is the passive process of particles spreading from areas of high concentration to areas of low concentration until they become evenly distributed throughout a space. We call diffusion passive because it requires no input of energy to occur: it’s caused by Brownian motion, the seemingly random movement of particles
