Thermal Energy Transfer

Front

What are convection currents?

Back

Convection currents are the movement of fluids (liquids and gases) caused by differences in temperature and density, leading to the transfer of thermal energy.

Front

What is conduction?

Back

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

Front

What is the difference between heat and temperature?

Back

Temperature measures the average kinetic energy of molecules, while heat is the total energy of molecular motion.

Front

How does heat transfer when touching a hot stove?

Back

Heat transfers from the stove to your hand by conduction.

Front

True or false: Heat moves from cooler objects to warmer objects.

Back

False. Heat moves from warmer objects to cooler objects.

Front

What is thermal energy?

Back

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

Front

What is radiation?

Back

Radiation is the transfer of energy through electromagnetic waves, such as light or infrared radiation.

Front

What is an example of convection?

Back

An example of convection is the heating of water in a pot, where hot water rises and cooler water sinks.

Front

What is a conductor?

Back

A conductor is a material that allows heat to pass through it easily, such as metals.

Front

What is an insulator?

Back

An insulator is a material that resists the flow of heat, such as rubber or wood.
