Thermal Energy Quiz

Define heat.

• The sensation or feeling of warmth

• The opposite of cold

• The property of having a temperature above 30°C

• The transfer of thermal energy from one substance to another

When you cook pancakes in a hot pan, determine which direction thermal energy moves.

• From the pancakes to the pan

• Between the pan and the pancakes, in both directions

• There is no movement of thermal energy

• From the pan to the pancakes

Select two options that complete the sentence. Two dinner plates are identical. One is placed in a hot oven and the other is placed in a cold fridge. After ten minutes, the plate in the oven has:

• more thermal energy

• less thermal energy

• particles with more kinetic energy

• particles with less kinetic energy

Identify why your hand feels cold as an ice cube melts on it.

• Thermal energy is transferred from your hand to the ice

• Cold energy is transferred from the ice to your hand

• Thermal energy can't transfer between your hand and ice

• Thermal energy is transferred from the ice to your hand

Identify the option that completes the definition. Conduction is the transfer of thermal energy:

• between substances in direct contact with one another

• from cooler objects to hotter ones

• by currents as hot substances rise and cold substances fall

• across empty space, such as from the Sun to Earth

Determine which of the following is the best example of conduction.

• Hot water rising above cold water

• Ironing a shirt

• Warming your hands by a fire

• An air conditioner cooling a room

Recall which type of energy is passed between particles during conduction.

• Chemical

• Speed

• Kinetic

• Light

A cold metal spoon is placed in a bowl of hot soup. Identify which of the following statements is correct.

• Thermal energy is not transferred between the soup and the spoon

• The particles in the spoon are moving faster than the particles in the soup

• Thermal energy is transferred from the spoon to the soup

• Thermal energy is transferred from the soup to the spoon

Select the option that best completes the following sentence. Insulators:

• do not allow thermal energy to easily flow through them

• allow thermal energy to easily flow through them

• are usually made of metal

• tend to feel very cold or hot when you touch them

Identify why it is safer to stir a pot of hot food with a wooden spoon instead of a metal spoon. Select two options.

• Metal is a good conductor and it can quickly transfer thermal energy to your hand and burn you

• Wood is a good insulator and does not transfer thermal energy quickly to your hand

• Metal is a good insulator and it can easily trap thermal energy from the hot food

• Wood is a good conductor and it can quickly transfer thermal energy away from your hand
