Thermal Energy Quiz

What is the main difference between heat and thermal energy?

• Heat is a substance, while thermal energy is a form of energy.

• Heat can be destroyed, but thermal energy cannot.

• Heat is the total energy of all moving particles, while thermal energy is always in motion.

• Heat is thermal energy that is being transferred from one place to another.

According to the law of conservation of energy, what happens to energy when it changes form?

• Energy is created.

• Energy is destroyed.

• Energy is transferred into heat only.

• Energy is neither created nor destroyed; it simply changes form.

Why does a lake have greater thermal energy than a glass of water at the same temperature?

• Because the lake has fewer particles than the glass of water.

• Because the lake's particles are in more motion than those in the glass.

• Because the lake contains many more particles than the glass of water.

• Because the temperature of the lake is higher than that of the glass of water.

What happens to the particles in a solid metal frying pan when it is placed on a hot burner?

• The particles stop moving.

• The particles in the pan move at a slower speed.

• The particles in the pan move at a greater average speed and therefore have greater thermal energy.

• The particles in the pan change from solid to liquid.

Which of the following can transfer thermal energy by conduction?

• Solids only

• Liquids only

• Gases only

• Solids, liquids, and gases

What is the reason kitchen hoods are placed above the stove and chimneys above fireplaces?

• To carry smoke and fumes sideways

• To make the room warmer

• Because hot air rises

• To prevent the spread of fire
