What is heat flow?

Back

Heat flow is the movement of thermal energy from one object or area to another, typically from a hotter object to a cooler one.

Front

How does heat flow between two objects?

Back

Heat flows from the object with a higher temperature to the object with a lower temperature until they reach thermal equilibrium.

What happens to ice cream left on a plate?

Back

The ice cream gains heat from the surrounding air, causing it to melt.

Front

What is thermal equilibrium?

Back

Thermal equilibrium is the state reached when two objects in contact no longer transfer heat to each other because they are at the same temperature.

Front

If object A is hotter than object B, which way will heat flow?

Back

Heat will flow from object A to object B.

Front

What is conduction?

Back

Conduction is the transfer of heat through a material without the movement of the material itself, often occurring in solids.

Front

What is convection?

Back

Convection is the transfer of heat through fluids (liquids and gases) caused by the movement of the fluid itself.

Front

What is radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves, such as sunlight, and does not require a medium.

Front

What is an example of conduction?

Back

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

Front

What is an example of convection?

Back

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