Grade 5 Thermal Energy Quiz

What is conduction of thermal energy?

• Transfer of heat through air particles

• Transfer of heat through sound waves

• Transfer of heat through electromagnetic waves

• Transfer of heat through direct contact between particles of a substance

Give an example of conduction of thermal energy.

• Touching a metal spoon that has been sitting in a hot cup of tea

• Mixing cold and hot water together

• Blowing on a hot bowl of soup

• Putting ice in a glass of water

What is convection of thermal energy?

• Transfer of heat through sound waves

• Transfer of heat through the movement of fluids

• Transfer of heat through solid objects

• Transfer of heat through electromagnetic waves

Explain how convection of thermal energy occurs.

• Convection of thermal energy happens when the temperature of a substance remains constant

• Thermal energy is transferred through electromagnetic waves

• Warmer, less dense air or liquid rises, and cooler, denser air or liquid sinks

• Convection of thermal energy occurs due to the rotation of the Earth

How does insulation help in conserving thermal energy?

• By reflecting the heat away

• By generating more heat

• By increasing the transfer of heat

• By reducing the transfer of heat

Name a material that is a good insulator of thermal energy.

• Wood

• Fiberglass

• Copper

• Aluminum

What is thermal energy transfer?

• The transfer of sound energy from one object to another

• The movement of heat from one object to another

• The movement of electrical energy through a circuit

• The conversion of light energy into heat energy

Explain the process of thermal energy transfer.

• Thermal energy transfer happens by telekinesis and telepathy.

• Thermal energy transfer occurs through conduction, convection, and radiation.

• Thermal energy transfer occurs through photosynthesis and respiration.

• Thermal energy transfer is caused by the rotation of the Earth and the movement of the tides.

What is temperature?

• The speed of an object

• A measure of the average kinetic energy of the particles in an object or substance.

• The amount of water in an object

• The color of an object

How is temperature measured?

• By counting the number of clouds in the sky

• Using a ruler

• Guessing based on how hot or cold it feels

• Using a thermometer
