Question

Describe a simple experiment to illustrate the existence of inter-molecular spacing.

Answer 1

Experiment:

• Take 100 ml of water in a measuring cylinder.
• Add 20 grams of salt in water gently and stir it well so as to dissolve the salt well in water.
• It is noticed that the level of water does not change.
• It shows that the particles of salt occupy spaces between the particles of water. Hence, it verifies the existence of intermolecular spacing.
