Thermal Energy

Front

What is thermal energy?

Back

The motion of atoms or molecules within a substance.

Front

What is kinetic energy?

Back

Energy of motion.

Front

What is a liquid?

Back

Matter in which atoms are constantly moving around and bumping into each other.

Front

What is condensation?

Back

The process when matter loses thermal energy and changes from a gas to a liquid.

Front

What is a solid?

Back

Matter in which atoms are closely spaced and vibrate in a fixed position.

Front

What happens to thermal energy when a substance is heated?

Back

Thermal energy increases, causing atoms to move faster.

Front

What is the relationship between temperature and thermal energy?

Back

Temperature is a measure of the average kinetic energy of particles in a substance.

Front

What is a gas?

Back

Matter in which atoms are far apart and move freely.

Front

How does thermal energy transfer occur?

Back

Through conduction, convection, and radiation.

Front

What is conduction?

Back

The transfer of thermal energy through direct contact between materials.
