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.

Why are most cooking pots in Noah's kitchen made of metal?

• Metal is a good conductor allowing heat to be distributed around the food.

• Metal helps food hold onto its flavors more by trapping molecules.

• Any other material would not withstand the heat.

• Other materials may be too light and flimsy causing the food to burn.
