II. Agitating the mixture
III. Placing the mixture in an ice bath

• A. I only
• B. II only
• C. I and II only
• D. I and III only

Answer 1

Crushing the solid into smaller pieces and agitating the mixture, both will help in increasing the random movement of solid particles in water.

Thus, the solid will easily get dissolved in water.
