Thermal Energy - Heat Transfer

Front

What is heat transfer by conduction?

Back

Heat transfer by conduction happens when two objects are touching and heat moves from one object into the next object.

Front

What is heat transfer by convection?

Back

Heat transfer by convection happens when there is a circulation of hot air/water rising and cold air/water sinking.

Front

In which direction does heat always move?

Back

Heat always moves from something hot/warm toward something cold/cool.

Front

What type of heat transfer occurs when feet get warm while in hot sand on the beach?

Back

This is an example of conduction.

Front

What are good insulators of thermal energy?

Back

Wool, feathers, cotton, and Styrofoam are all examples of good insulators of thermal energy.

Front

Define thermal energy.

Back

Thermal energy is the total kinetic energy of particles in a substance, which is related to temperature.

Front

What is the difference between conduction and convection?

Back

Conduction is heat transfer through direct contact, while convection is heat transfer through the movement of fluids (liquids or gases).

Front

What role do insulators play in heat transfer?

Back

Insulators slow down the transfer of thermal energy, keeping heat in or out of a space.

Front

Give an example of conduction in everyday life.

Back

An example of conduction is touching a hot stove and feeling the heat transfer to your hand.

Front

What is the principle of thermal equilibrium?

Back

Thermal equilibrium is the state in which two objects in contact with each other reach the same temperature and no heat flows between them.
