Which number on the diagram is thermal radiation

• Number 1

• Number 2

• Number 4

What does heat try to do as it flows between two objects.

• Flow until there is no heat left
• Flows until both object have reached absolute zero
• Flows from the hot object into the cold object
• Equalize the temperature between the two objects

Heat energy flowing between two objects that are touching or by molecules colliding.

• Conduction

• Convection

• Heat Flow

Heat energy flowing as a current in a fluid (fluids are air, water, and magma)

• Conduction

• Convection

• Thermal Radiation

• Heat Flow

Match each number on the convection diagram to its correct description from the key.

• 6

• The denser fluid sinks back down toward the heat source.

• 5

• A fluid is heated by a heat source which expands in volume, becomes less dense and rises until it hits a barrier that stops it.

• 1

• The heat source which heats the fluid.

• 3

• A barrier which stops the rising fluid.

• 2

• Unable to rise, the fluid travels laterally (sideways) losing heat and volume and becoming more dense.
