Question

If state S1 has the highest kinetic energy, S2 has indefinite shape but definite volume and state S3 has the strongest inter-particle forces of attraction then processes B, C and A respectively are

Answer 1

Explanation:

A is a solid

B is a liquid

C is a gas

Matter has three states: Solid, Liquid and gas. They can be differentiated on the basis of following parameters:

1. Inter molecular forces of attraction

2. Kinetic energy levels

3. Definite shape and volume

4. Ability to flow

Solids:

Solids have highest inter molecular force of attraction, the molecules are closely packed giving them rigid structure and fixed volume. Kinetic energy is very low because of their close packing. They do not have the ability to flow.

Liquids:

Liquids have moderate inter molecular forces of attraction, the molecules have loose packing giving them indefinite shape but fixed volume. Kinetic energy levels lie between solids and gases. They have fluid nature.

Gases:

Gaseous state has lowest inter molecular forces of attraction, the molecules are very loosely packed giving them neither fixed shape nor fixed volume.

Kinetic energy levels are highest. hey have the ability to flow.
