What causes the circulation of air?

• Air in the atmosphere is heated by the Sun and sinks to the ground.

• The ground is heated by the Sun and then heats the air, causing the air to rise.

• Air loses heat to the ground and then rises upward to obtain more energy.

• The Sun heats the clouds which forces the cooler air to move away and sink.

Which best explains why a refrigerator is usually not made completely out of metal?

• Metal will not transfer heat, which allows the refrigerator to remain cool.

• Metal easily transfers heat, which would warm the inside of the refrigerator.

• Metal would heat up quickly on the outside, making the door too hot to touch.

• Metal cools quickly, causing the refrigerator to be too cold and freeze the food inside.

A student places a cup of cold water on a counter in a hot room. After a short time, the student notices that the water in the cup is no longer cold. Which best explains why the water in the cup is no longer cold?

• The coldness of the water transferred to the air, making the water in the cup warmer.

• The coldness of the water was conducted to the cup, making the water in the cup warmer.

• The heat from the air transferred to the water in the cup, making the water in the cup warmer.

• The heat from the air caused the cold water in the cup to condense, making the water warmer.
