HMH Energy I 2.2 Temperature and Heat

Front

What is conduction?

Back

Conduction is the transfer of heat through direct contact between particles, where particles bump into each other.

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases) caused by differences in temperature and density.

Front

What is radiation?

Back

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

Front

What device is used to measure temperature?

Back

A thermometer is a device used to measure temperature.

Front

What does temperature measure?

Back

Temperature measures the average kinetic energy of molecules in a substance.

Front

What is the difference between heat and temperature?

Back

Heat is the total energy of all the particles in a substance, while temperature is the average kinetic energy of those particles.

Front

What is an example of conduction?

Back

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

Front

What is an example of convection?

Back

An example of convection is boiling water, where hot water rises and cooler water sinks.

Front

What is an example of radiation?

Back

An example of radiation is feeling warmth from the sun on your skin.

Front

What happens to particles during conduction?

Back

During conduction, particles collide and transfer energy to neighboring particles.
