Chemistry: Heat Transfer P7

Front

What is the relationship between molecular movement and temperature?

Back

The quicker a molecule moves, the warmer it is.

Front

What is a material that does NOT conduct heat well called?

Back

Insulator

Front

How does heat transfer occur when holding hands with someone warmer?

Back

The heat energy from your friend's hand transferred to your hand through conduction.

Front

What is the measure of average kinetic energy of all the particles within an object called?

Back

Temperature

Front

In heat transfer, from where does heat always flow?

Back

Heat always flows from the hotter substance to the colder substance.

Front

What is conduction?

Back

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

Front

What is convection?

Back

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

Front

What is radiation in the context of heat transfer?

Back

Radiation is the transfer of heat through electromagnetic waves without the need for a medium.

Front

What happens to the temperature of a substance when it absorbs heat?

Back

The temperature of the substance increases.

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.
