Question

name the process associated with the following:. a)dry ice is kept at room temperature and at one atmospheric pressure. 2)a drop of ink placed on the surface of water contained in a glass spreads throughout the water. 3) a potassium permanganate crystal is in a breaker and water is poured into the beakar with stirring.​

Answer 1

Answer:

(a) The process is sublimation because when dry ice (solid CO2) is kept at room temperature at one atmospheric pressure, it sublimes leaving no residue. (b) This process is diffusion because in diffusion, mixing of one substance (ink) into another substance (water) goes on until a uniform mixture is formed.
