Thermal Energy Test

Front

What is thermal energy?

Back

Thermal energy is the energy that comes from the temperature of matter. It is the total kinetic energy of the particles in an object.

Front

What is conduction?

Back

Conduction is the transfer of thermal energy through direct contact between materials. For example, a metal spoon getting hot in a pot of soup.

Front

What is convection?

Back

Convection is the transfer of thermal energy through the movement of fluids (liquids or gases). An example is warm air rising and cool air sinking.

Front

What is radiation?

Back

Radiation is the transfer of thermal energy through electromagnetic waves. An example is feeling the warmth of the sun on your skin.

Front

What is an insulator?

Back

An insulator is a material that does not conduct thermal energy well. Examples include rubber, wood, and plastic.

Front

What is a conductor?

Back

A conductor is a material that allows thermal energy to pass through it easily. Examples include metals like copper and aluminum.

Front

How do particles behave when heated?

Back

As particles are heated, they gain energy and move faster, causing them to spread apart.

Front

What happens to the temperature of a substance when it absorbs thermal energy?

Back

The temperature of the substance increases as it absorbs thermal energy.

Front

What is the difference between conduction and convection?

Back

Conduction occurs through direct contact, while convection involves the movement of fluids.

Front

What is an example of radiation in everyday life?

Back

An example of radiation is feeling warmth from a campfire or the sun.
