Energy Transfer

Sarah is investigating the transfer of energy in the form of heat. One process that transfers energy between two objects is conduction. Which statement is not true about conduction?

• It can transfer energy through empty space.

• It requires direct contact between the objects.

• It involves a transfer of energy in the form of heat.

• It results in a change of temperature in both objects.

During the day, the portions of Earth’s surface that receive sunlight absorb energy in the form of heat. During the night, Earth’s surface radiates this energy back into space. What is the main form of radiation released by Earth at night?

• visible light

• gamma rays

• infrared radiation

• ultraviolet radiation

As water is heated by the sun, it becomes less dense and rises. What causes the decrease in the density of warming water?

• The water particles move faster, causing the water to expand.

• The water particles move slower, causing the water to expand.

• The water particles move faster, causing the water to contract.

• The water particles move slower, causing the water to contract.
