A plastic spoon that has a temperature of 78 degrees F is placed into a bowl of soup that has a temperature of 84 degrees F. Which of these correctly describes what will happen?

• Energy as heat moves from the spoon to the soup.

• Energy as heat does not move, because the spoon is plastic.

• Energy as heat moves from the soup to the spoon.

• Energy as heat does not move, because the temperature difference is too small.

Leanne created the following diagram to show the process that warms the air above a lake. She decided to label each step with the energy transfer that is happening. Which step should Leanne label as conduction?

• Step 1

• Step 2

• Step 3

• Step 4

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.
