Question

3. In the given experimental set-up, a dye is placed at the bottom of a beaker filled with water. After some time, the entire water in the beaker became coloured uniformly as shown in figure D. D C с B. А (a) Name and define the phenomenon shown in this experiment. (b) In the above figure, two kinds of molecules are shown: larger and smaller. Mention which molecules are of the solute and which are of solvent? (c) If all the bigger molecules in A are enclosed in a permeable membrane, what will be the nature of movement of the molecules, if any?
*pls I want the Ans right now ​

Answer 1

Answer:

(a) The phenomenon is diffusion. Diffusion is the movement of the molecules or atoms of a substance from the region of higher concentration to the region of lower concentration.

(b) Larger Molecules are solute that is dye and the Smaller Molecules are solvent that is water.

(c) If the bigger molecules are enclosed in a permeable membrane, the nature of movement becomes passive which means that they starts to move from higher concentration region to lower concentration region.

Answer 2

Explanation:

A = Diffusion is the movement of molecules from higher concentration to the region of their lower concentration without using energy .

B = Solvent = Larger molecules

Solvent = Smaller molecules

C = Passive transport will be the nature of movement of molecules which will not allow molecules to move across membrane .
