Unit 4: Thermal Energy (I.6C & I.6D)

Front

What is a Closed System?

Back

A system in which the total amount of energy remains constant as energy conversions occur.

Front

What type of energy is released when water vapor condenses to form liquid?

Back

Thermal energy.

Front

What is Radiation in terms of heat transfer?

Back

The only type of heat transfer that doesn't require a medium and can occur through a vacuum.

Front

What type of heat transfer occurs when you hold a hot cup of coffee?

Back

Conduction.

Front

How does thermal energy move?

Back

From an object with higher kinetic energy to an object with lower kinetic energy.

Front

What is Conduction?

Back

The transfer of heat through direct contact between materials.

Front

What is Convection?

Back

The transfer of heat through the movement of fluids (liquids or gases).

Front

What is the difference between Conduction and Convection?

Back

Conduction involves direct contact, while convection involves the movement of fluids.

Front

What is an example of Radiation?

Back

The heat from the sun warming your skin.

Front

What is Thermal Equilibrium?

Back

A state in which two objects in contact no longer transfer heat, as they are at the same temperature.
