The front door of a house is made of steel. When it is warm outside, the door sticks and it is difficult to open or close. When the weather is cool, the door does not stick. Which statement best explains the difference in the behavior of the door when the weather is warm compared to when it is cool?

• When a material contracts, it increases in volume due to an increase in kinetic energy.

• Different materials expand and contract at the same rates due to the kinetic energy being the same.

• Thermal expansion makes the door fit better when it is cooler due to a decrease in kinetic energy.

• The metal in the door expands when it becomes warm due to an increase in kinetic energy and contracts when it is cooler.

Adisyn sits by a fire and watches the logs burn bright and feels the warmth of the fire. Which one of these statements is true about the amount of energy transformed in the camp fire?

• The Law of Conservation of Energy does not apply to these transformations.

• The chemical energy in the logs is lost during the transformations.

• The amount of heat and light energy released equals the amount of chemical energy that is burned.

• The fire is hotter than the logs were, so energy is gained in this transformation.
