How does heat travel from one heated object to unheated object?

• The air over heated object travels to the other object and makes it warm.

• Some of the heat converts to radiation and travels to unheated object.

• Electrons within heated object started moving, distributing heat consistently in both objects.

• The molecular movement in heated object transfers heat energy to molecules in unheated object.

Why do some animals need a layer of fat in the winter?

• It helps them swim in the ocean.

• It insulates and keeps them warm.

• Females use the fat to feed the babies.

• Only males have fat and it is used to attract a mate.

Why does the upper story of a house typically stay warmer than the lower story?

• The warm air expands and rises with convection.

• The warm air expands and sinks with convection.

• The warm air contracts and rises with conduction.

• The warm air contracts and sinks with conduction.
