What happens to the particles in a liquid?

• They are far apart and move freely.

• They are close together but can move past each other.

• They are tightly packed and cannot move.

• They are in a fixed position and do not move.

What happens to the particles in a gas?

• They are tightly packed and vibrate in place.

• They are far apart and move freely.

• They are arranged in a fixed structure.

• They are clustered together and move slowly.

What is an electric circuit?

• An electric circuit is a complete path through which electricity can flow.

• An electric circuit is a device that stores electrical energy.

• An electric circuit is a type of electrical appliance.

• An electric circuit is a method of generating electricity.

What must an electric circuit have for electricity to flow?

• A complete path.

• A broken path.

• An open switch.

• A high voltage source.

What type of energy causes air to vibrate?

• Light energy

• Nuclear energy

• Sound energy

• Thermal energy

What is sound energy?

• Sound energy is produced when objects vibrate, causing air particles to move.

• Sound energy is a form of energy that can be seen but not heard.

• Sound energy is generated by the movement of light particles.

• Sound energy is the energy stored in chemical bonds of molecules.

What is the difference between solids, liquids, and gases?

• Solids have a definite shape and volume, liquids have a definite volume but take the shape of their container, and gases take both the shape and volume of their container.

• Solids and liquids both have a definite shape, while gases have a definite volume.

• Liquids have no definite shape or volume, while solids and gases do.

• Gases have a definite shape and volume, while solids and liquids do not.

What is thermal energy?

• The energy that comes from the temperature of matter.

• The energy stored in chemical bonds.

• The energy associated with the motion of particles in a solid.

• The energy released during nuclear reactions.

What is light energy?

• Energy that is visible to the human eye and is produced by light sources.

• Energy that is invisible and cannot be detected by the human eye.

• Energy that is produced by sound waves and can be felt as heat.

• Energy that is stored in food and released during digestion.

What happens to the particles in a solid?

• They are loosely arranged and move freely.

• They are closely packed together and vibrate in place.

• They are spread out and can flow easily.

• They are in a gaseous state and move rapidly.
