What is thermal equilibrium?

Back

Thermal equilibrium is the state in which two objects in contact with each other do not exchange heat, meaning they are at the same temperature.

Front

Where does conduction occur best?

Back

Conduction occurs best in solids.

Front

What type of heat transfer is involved in the Gulf Stream?

Back

The Gulf Stream involves convection, as it is the movement of warm ocean water.

Front

What happens to heat transfer when two objects have the same temperature?

Back

The net transfer of heat is zero when both objects have the same temperature.

Front

How does heat transfer occur between warmer and cooler objects?

Back

Heat transfers from the warmer object to the cooler object until thermal equilibrium is reached.

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 conduction?

Back

Conduction is the transfer of heat through direct contact between materials, typically occurring in solids.

Front

What is radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves, such as sunlight.

Front

What is an example of conduction?

Back

An example of conduction is a metal spoon getting hot when placed in a hot pot of soup.

Front

What is an example of convection?

Back

An example of convection is warm air rising and cool air sinking in a room.
