Answer 1

Aim: to observe the effect of temperature on the solubility of non volatile substances in a solvent

Explanation:

MATERIALS REQUIRED: sugar, tumblers (2), cold or normal water, hot water, stop watch PROCEDURE: 1. Take two tumblers. One filled with cold or normal water and another filled with hot water.

2. Dissolve one spoon of sugar in each of the tumbler using a stirrer (spoon).

3. Record the time taken for dissolution in both the cases.

OBSERVATION :with increase in the temperature there is decrease in the solubility of the substance. The time taken to get dissolved in the solvent increases
