Conduction can only occur between two objects when _________.

• one object is less dense than the other.

• both objects are in physical contact with each other.

• one of the objects is made of a metal.

• both objects are exactly the same temperature.

Look at the picture provided. In the situation illustrated, how will heat energy move? Heat energy will be transferred from –

• the water to the hot plate by convection.

• the water to the hot plate by conduction.

• the hot plate to the water by convection.

• the hot plate to the water by conduction.

Radiation is a method of thermal energy transfer. It refers to the transfer of heat energy that moves –

• through empty space.

• when objects touch.

• only through solids.

• the motion of fluids.

Three metal cubes with different temperatures are placed side-by-side as shown in the picture provided. Which of the following describes a way in which heat energy will be transferred by conduction.

• Sample 1 to Sample 2

• Sample 3 to Sample 2

• Sample 3 to Sample 1

• Sample 2 to Sample 3

Reed is trying to create a model that represents the movement of the Earth’s crust. He places a beaker with water in it on a heating source that has two wood blocks floating on the surface of the water. As the water heats up it rises to the surface causing the blocks to move away from each other.

What type of heat transfer is occurring as the water is moving as shown in the diagram?

• Convection

• Conduction

• Radiation

• Specific
