Mikhayla has 2 pieces of metal. She places one in the freezer at 5°C and one in a toaster oven at 90°C. After 2 hours, she takes them out and places both of them in a beaker full of boiling water. Which of the following best describes how some of the heat will initially move in this system?

• Heat will flow from the hot metal into the boiling water.

• Heat will flow from the boiling water into the frozen metal.

• Heat will flow from the frozen metal into the hot metal.

• Heat will flow from the frozen metal into the glass beaker.

Kymbrece heats a pot of water to cook pasta. What may happen as a result of adding heat?

• When the water begins to boil, some of the water molecules gain enough energy to change into a gas.

• When the water begins to boil, some of the water molecules lose energy and change into a gas.

• The water gains energy and the temperature of the pasta remains the same.

• The water and the pasta both lose energy.
