Jackie places a cup of cold water on a counter in a warm room. After a short time, she 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.

Jean has a wooden rod, a steel rod, and a glass rod. How could she compare the materials to find out which transfers thermal energy BEST?

• Place the rods in ice water to find out which loses the most heat.

• Place the three rods in a freezer to find out which becomes the coldest.

• Place the rods in very hot water to see which becomes hot the fastest.

• Place the rods on a table in a warm room and find out which feels warmest after a period of time.

Misty was having trouble opening a new glass jar of pickles. Her father told Misty to hold the metal lid of the jar under running hot water for a few seconds, then try again. Then the lid opened easily. What is the MOST likely reason Misty’s father suggested using hot water to loosen the lid?

• Glass contracts when it is heated.

• Metals expand when they are heated.

• Metals are easier to grip when they are warm.

• Hot water reduces friction between metal and glass.

Heather fills a bicycle tire with air on a very hot day. The next day, the temperature drops and it is much cooler. Heather notices that the bicycle tire is almost flat. What best explainswhy the tire is flat?

• The cooler temperature caused the air in the tire to contract, making the tire appear flat.

• The cooler temperature caused the air in the tire to expand, which put a hole in the tire, causing it to go flat.

• The cooler temperature caused the air in the tire to freeze, making the tire flat.

• The cooler temperature caused the metal part of the bicycle to expand, putting a hole in the tire

  and making it go flat.
