Unit 2 - Energy Test

Front

What happens to water molecules in the air on a muggy day when they strike our bodies?

Back

They transfer some of their kinetic energy to us.

Front

In which direction does heat flow when an ice cap melts?

Back

From the water to the ice cap.

Front

True or False: Insulators can protect us from getting burned while cooking because heat does not flow through them.

Back

True.

Front

What type of circuit will NOT work?

Back

An open circuit.

Front

Will this circuit work? (Yes/No)

Back

No.

Front

What is kinetic energy?

Back

The energy an object has due to its motion.

Front

What is thermal energy?

Back

The total energy of all the particles in an object, related to temperature.

Front

Define insulator.

Back

A material that does not allow heat or electricity to pass through it easily.

Front

What is a closed circuit?

Back

A complete electrical path that allows current to flow.

Front

What is the principle of heat transfer?

Back

Heat flows from a region of higher temperature to a region of lower temperature.
