Thermal Energy Transformations

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 process of heat transfer through direct contact between materials. It occurs when particles collide with each other.

Front

What is convection?

Back

Convection is the transfer of heat through fluids (liquids and gases) caused by the movement of the fluid itself.

Front

What is radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves, such as light. It does not require a medium to travel.

Front

How does temperature affect particle movement?

Back

As temperature increases, particles move faster. In hot substances, particles have more energy and move more quickly.

Front

What is an example of conduction?

Back

An example of conduction is when a metal spoon gets hot after being placed in a pot of hot soup.

Front

What is an example of convection?

Back

An example of convection is the warm air rising and cool air sinking in a room, creating a circulation of air.

Front

What is an example of radiation?

Back

An example of radiation is feeling the warmth of the sun on your skin, even when you are not in direct contact with it.

Front

What happens to the thermal energy of an object when it is heated?

Back

When an object is heated, its thermal energy increases, causing its particles to move faster.

Front

What is the role of thermal conductors?

Back

Thermal conductors are materials that allow heat to pass through them easily, such as metals.
