âKrystal is exploring the properties of iron. She takes a large iron nail and finds that the nail does not attract other metal objects. Next, she uses a battery and copper wire to transform the nail into an electromagnet. When she connects the circuit, the nail becomes magnetic and can pick up small metal objects like paper clips. This is shown in the illustration below.
What best describes what has happened to the iron in the nail that causes it to become magnetic?
A physical change has occurred, because the chemical properties of iron remain the same.
A physical change has occurred, because the chemical attraction between the iron and paper clips.
A chemical change has occurred, because the chemical energy in the battery is transformed into magnetic energy in the iron.

The students in Ms. Ramirez's science class are classifying different types of reactions. They have divided the reactions into two columns as shown below. Use the table to answer
the questions that follow.
Why are the reactions listed in Column A classified as chemical reactions?
Carbon dioxide (CO2) is a substance that is a gas at room temperature. At temperatures below 78°C, carbon dioxide condenses into a white solid known as dry ice. At normal atmospheric pressures, dry ice changes directly from a solid to a gas without passing through a liquid
phase when its temperature increases. This process is called sublimation. Which of the following best describes the process of sublimation?
