Sheela, Saima and Ravi have to dissolve maximum amount of sugar in the same amount of milk so as to win in a game. Ravi took hot boiling milk while Saima took ice cold milk. Sheela managed to get milk at room temperature. Whom do you think would win the game and why?

The solubility of solids in liquids increases with temperature. Saima will be able to dissolve the minimum amount of sugar in ice-cold milk.

Sheela will be able to dissolve more sugar than Saima since the milk is at room temperature.

Ravi would win the game because he would be able to dissolve the maximum amount of sugar in hot, boiling milk.

Solubility: Solubility is the ability of a solute to dissolve in a solvent. For example, salt dissolves in water.

Factors affecting solubility: 

1. Temperature

2. Surface area

3. Concentration

4. Pressure

An increase in the temperature of the liquid increases the solubility, as the temperature is directly proportional to the solubility. An increase in pressure also increases the solubility of solids in liquids.
