Answer 2

Answer:

The following given properties are distinguished in a tabular form in the attached image.

Explanation:

Intermolecular forces :

• Definition:

The electromagnetic forces of attraction and repulsion that act between atoms and other types of neighbouring particles, such as atoms or ions, are examples of intermolecular forces.

• Because of extraordinarily strong intermolecular interactions between molecules, solids have a fixed volume. Intermolecular forces are greater in liquids than in gases, but they are weaker in solids. Intermolecular forces are essentially non-existent in gases. As a result, no specific volume can be determined.

Density:

• Solids have a higher density than liquids, which are in turn heavier than gases.
• The particles of the solid are relatively close together, with little space between them.
• The particles in a liquid are typically still in contact, although there are occasional gaps between them.

Fluidity :

• Solids are hard by nature and hence do not exhibit fluidity.
• Liquids can flow, hence they have fluidity, but it is less than that of gases.
• Because gases flow more easily than liquids, they have the most fluidity.

Diffusion :

• In gases, liquids, and solids, diffusion is a natural occurrence.
• The rate of diffusion increases as the temperature of the dispersed substance rises.
• Diffusion occurs most quickly in gases and takes the longest in solids.

Kinetic energy of particles at a given temperature :

• It is the energy of mass in motion in its most fundamental form.
• Kinetic energy can never be negative and is a scalar quantity, meaning it only supplies the magnitude rather than the direction.
• Solids vibrate the least because they have the lowest kinetic energy.
• Because liquids have more kinetic energy than solids, particles in liquids move past one another. Gases have the most kinetic energy, thus they float around.
