Part 1: Thermal Energy Test

Front

What is thermal energy?

Back

Thermal energy is the total kinetic energy of the particles in a substance, which is related to its temperature.

Front

What is the difference between conduction, convection, and radiation?

Back

Conduction is heat transfer through direct contact, convection is heat transfer through fluid movement, and radiation is heat transfer through electromagnetic waves.

Front

What is a conductor?

Back

A conductor is a material that allows heat to flow through it easily, such as metals like copper and aluminum.

Front

What is an insulator?

Back

An insulator is a material that resists the flow of heat, such as wood, wool, or plastic.

Front

What happens to heat flow when two objects at different temperatures come into contact?

Back

Heat flows from the warmer object to the cooler object until they reach the same temperature.

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases) caused by differences in temperature and density.

Front

What is radiation?

Back

Radiation is the transfer of heat energy through electromagnetic waves, which can occur in a vacuum.

Front

What is the role of temperature in thermal energy transfer?

Back

Temperature determines the direction of heat flow; heat moves from areas of higher temperature to areas of lower temperature.

Front

What is the significance of the Mauna Loa volcano in climate studies?

Back

The Mauna Loa volcano is significant for its long-term monitoring of atmospheric carbon dioxide levels, which helps in understanding climate change.

Front

How does air temperature vary in a room?

Back

Air temperature tends to be warmer near the ceiling due to convection, as warm air rises and cooler air sinks.
