What is electrical energy?

Back

Electrical energy is the energy caused by the movement of electrons. It powers devices like lights, computers, and appliances.

Front

What is thermal energy?

Back

Thermal energy is the energy that comes from the temperature of matter. It is the energy that causes the particles in an object to move.

Front

What is density?

Back

Density is the mass of an object divided by its volume. It tells us how much matter is packed into a certain space.

Front

How can you determine if one liquid is denser than another?

Back

You can determine density by comparing how much mass is in a given volume. The liquid with more mass in the same volume is denser.

Front

What happens in a closed circuit?

Back

In a closed circuit, electricity flows through the circuit, allowing devices like lightbulbs to operate.

Front

What is an insulator?

Back

An insulator is a material that does not allow heat or electricity to pass through easily. Examples include rubber and glass.

Front

What is the purpose of a switch in a circuit?

Back

A switch controls the flow of electricity in a circuit. When it is closed, electricity flows; when it is open, electricity stops.

Front

What is the relationship between electrical energy and light?

Back

Electrical energy can be converted into light energy, as seen in lightbulbs, where electricity causes the filament to glow.

Front

What is the best way to keep liquids hot?

Back

Using a good insulator, like foam or thick fabric, can help keep liquids hot by reducing heat loss.

Front

What is the role of a lightbulb in a circuit?

Back

A lightbulb converts electrical energy into light energy, allowing us to see.
