What is the Particle Theory?

Back

The Particle Theory states that all matter is made up of tiny particles that are in constant motion. The properties of matter depend on the arrangement and movement of these particles.

What happens to the volume of water when an object is placed in it?

Back

The volume of water increases by the volume of the object placed in it, demonstrating the principle of displacement.

What is density?

Back

Density is the mass of a substance divided by its volume. It determines how heavy a substance is for a given space.

How do particles behave in a solid?

Back

In a solid, particles are tightly packed together and vibrate in place, maintaining a fixed shape and volume.

Front

How do particles behave in a liquid?

Back

In a liquid, particles are close together but can move past one another, allowing liquids to flow and take the shape of their container.

Front

How do particles behave in a gas?

Back

In a gas, particles are far apart and move freely, filling the entire volume of their container.

What is the process of dissolving?

Back

Dissolving is the process where a solute (like sugar) mixes with a solvent (like water) to form a solution, where the solute becomes evenly distributed.

What is an example of a substance with high density?

Back

Honey is an example of a substance with high density compared to water and lamp oil.

Front

What is an example of a substance with low density?

Back

Lamp oil is an example of a substance with low density compared to water and honey.

What happens to sugar when it is added to water and stirred?

Back

The sugar dissolves in the water, becoming part of the solution and no longer visible.
