Give the ideas that you have at this time about how energy relates to differences between solids, liquids and gases.

The energy content of substances is related to the physical state in which the substance exists. Molecules of gases are always in motion as they possess very high kinetic energy, hence, they exist as gases. Liquid molecules are less energetic than gas molecules, hence they have less flow than gases. Solid molecules on the other are fixed at a place because they possess very low kinetic energy and can only vibrate about their fixed positions.

Explanation:

The three states in which matter exist are solid, liquid and gas.

Solids are made of molecules that are closely packed together and held together by strong intermolecular forces. The particles in a solid possess very low kinetic energy and are not free to move about but can only vibrate and rotate about their fixed positions.

Liquids particles are able to  move about as they possess enough kinetic energy to limit or reduce the strength of the intermolecular forces binding them together. Thus, liquids can flow.

The particles in a gas are relatively far apart and possess kinetic energy more than the particles of a liquid or solid. The intermolecular forces binding particles of gas together are weak due to the very high kinetic energy of yhe gas particlest
