i.Does the rate of mixing changes with temperature? Explain why?
Yes rate of mixing of particles of matter changes with temperature.
Particles of matter are continuously moving, that is, they possess kinetic energy. The particles of matter intermix on their own with each other. They do so by getting into the spaces between the particles. This intermixing of particles of two different types of matter on their own is called diffusion. As the temperature rises, particles move faster. So, we can say that with increase in temperature the kinetic energy of the particles increases, which leads to increase in the inter mixing of particles and diffusion becomes faster.
