Amplify - Thermal Energy Review

Front

What happens when hot and cold air make contact?

Back

The hot air will lose kinetic energy.

Front

What is a balanced state in which a system is stable, such as when two or more samples are at the same temperature?

Back

Equilibrium.

Front

Which sample will transfer energy to the other if Sample A is hotter than Sample B?

Back

Sample B will transfer energy to Sample A.

Front

From which sample does energy always transfer?

Back

Energy will always be transferred from the hotter sample to the colder sample.

Front

What is the temperature when heat transfer is complete between two samples?

Back

12 degrees.

Front

What is thermal energy?

Back

Thermal energy is the total kinetic energy of particles in a substance.

Front

What is conduction?

Back

Conduction is the transfer of thermal energy through direct contact between materials.

Front

What is convection?

Back

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

Front

What is radiation?

Back

Radiation is the transfer of energy through electromagnetic waves.

Front

What is the role of temperature in thermal energy transfer?

Back

Temperature determines the direction of thermal energy transfer; energy moves from higher to lower temperature.
