Explanation

Muskan'a mother cut the vegetables into small pieces and put them into the sun (to get sunlight) for few hours so that they lose water by diffusion and evaporation and become dry.
(ii) She mixed common salt to the cut vegetables so that the cells of cut vegetables lose further water by exosmosis. Heating was done to evaporate the water. This is done to check the growth of microorgnisms such as bacteria and fungi on the vegetables.
(ii) Acetic acid is used as preservative, it kills the microorgarisms.
