conduction, convection, and radiation.

Front

What is conduction?

Back

Conduction is the transfer of thermal energy through direct contact between materials. It occurs when heat moves from a hotter object to a cooler one.

Front

What is convection?

Back

Convection is the transfer of thermal energy through the movement of fluids (liquids or gases). It occurs when warmer, less dense fluid rises and cooler, denser fluid sinks.

Front

What is radiation?

Back

Radiation is the transfer of thermal energy through electromagnetic waves. It does not require a medium and can occur in a vacuum.

Which of the following is NOT a type of thermal energy?

Back

A pool.

Which of the following is NOT an example of conduction?

Back

The sun.

Front

What happens to particles in a fluid when heated?

Back

They move faster and spread apart, causing the fluid to become less dense.
