Heat Transfer Flashcard

Front

What is conduction?

Back

Conduction is the process of heat transfer through direct contact between materials.

Front

What is convection?

Back

Convection is the transfer of heat through fluids (liquids or gases) caused by the movement of the fluid itself.

Front

What is radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves, which can occur in a vacuum.

Front

What happens to particles when heat is added?

Back

When heat is added, the particles of a substance move faster.

Front

What is thermal energy?

Back

Thermal energy is the energy that comes from the temperature of matter; it is the total kinetic energy of the particles in an object.

Front

What is heat transfer?

Back

Heat transfer is the movement of thermal energy from a warmer object to a cooler one.

Front

What is thermal equilibrium?

Back

Thermal equilibrium is the state in which two objects in contact do not exchange heat, meaning they are at the same temperature.

Front

What is the relationship between temperature and thermal energy?

Back

As the temperature of an object increases, its thermal energy also increases.

Front

What is an example of conduction?

Back

An example of conduction is a metal spoon getting hot when placed in a hot soup.

Front

What is an example of convection?

Back

An example of convection is warm air rising and cool air sinking in a room.
