Intro to Thermal Energy

Front

What happens to a substance when thermal energy is removed from it?

Back

The substance may freeze.

Front

In which direction does thermal energy always move?

Back

From a warmer area to a cooler area.

Front

What does temperature measure in terms of atomic motion?

Back

The average kinetic energy of the atoms in a substance.

Front

What type of chemical reaction can be used to heat up other substances?

Back

A chemical reaction that releases energy.

Front

Why do atoms have kinetic energy?

Back

Because they are always vibrating.

Front

What is thermal energy?

Back

The total kinetic energy of all the particles in a substance.

Front

What is the relationship between thermal energy and temperature?

Back

Temperature is a measure of the average kinetic energy of particles, while thermal energy is the total energy.

Front

What occurs during the process of conduction?

Back

Thermal energy is transferred through direct contact between materials.

Front

What is convection?

Back

The transfer of thermal energy through the movement of fluids (liquids and gases).

Front

What is radiation in the context of thermal energy?

Back

The transfer of thermal energy through electromagnetic waves.
