Name the process associated with the following (a) Dry ice is kept at room temperature and at one atmospheric pressure. (b) A drop of link placed on the surface of water contained in a glass spreads throughout the water. (c) A potassium permanganate crystal is in a beaker and water is poured into the beaker with stirring. (d) A acetone bottle is left open and the bottle becomes empty. (e) Milk is churned to separate cream from it. (f) Settling of sand when a mixture of sand and water is left undisturbed for some time. (g) Fine beam of light entering through a small hole in a dark room. Illuminates the particles in its paths.

As shown schematically in the figure , two vessels contain water solutions (at temperature T) of potassium permanganate (KMnO_(4)) of different concentrations n_(1)andn_(2)(n_(1)gtn_(2)) molecules per unit volume with Deltan=(n_(1)-n_(2)ltltn_(1) . When they are connected by a tube of small length and cross - sectional area s, KMnO_(4) starts to diffuse from the left to the right vassel through the tibe Consider the two collection of molecules to between as dilute ideal gases and the difference in their partial pressure in the two vassels causing the diffusion . The speed v of the molecules is limited by the viscous force -betav on each molecule, where beta is a constant . neglecting all terms of the order (Deltan)^(2) which of the following is / are correct ? ( k_(B) is the Boltzmann constant)
