Thermal Equilibrium TEK 6.9B

Front

What is Thermal Equilibrium?

Back

The condition where two substances in physical contact with each other exchange no heat energy and are at the same temperature.

Front

In which direction does heat energy transfer between two objects with different temperatures?

Back

Heat energy transfers from the hotter object to the cooler object.

Front

Heat always moves from _____________ to ______________.

Back

hot; cold

Front

What happens to a cold metal earring placed on a desk at room temperature?

Back

Both the earring and the desk will be at room temperature after a while.

Front

What is Convection?

Back

The transfer of thermal energy in a liquid or gas where the warmer substance rises and the cooler substance sinks, forming a current.

Front

What is Thermal Energy?

Back

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

Front

What is the difference between conduction and convection?

Back

Conduction is the transfer of heat through direct contact, while convection is the transfer of heat through the movement of fluids.

Front

What is Radiation?

Back

The transfer of energy through space by electromagnetic waves, such as light or heat from the sun.

Front

What is the role of temperature in thermal energy transfer?

Back

Temperature determines the direction of heat transfer; heat moves from areas of higher temperature to areas of lower temperature.

Front

What is an example of conduction?

Back

Touching a hot stove and feeling the heat transfer to your hand.
