Answer the following question given this paragraph: The Sun is made almost entirely of the elements hydrogen and helium. The Sun has no solid material. Most atoms in the Sun exist as plasma . Plasma is superheated gas with an electrical charge. Because the Sun is made of gases, it does not have a defined outer boundary. Like Earth, the Sun has an internal structure. The inner three layers make up what we would actually call "the Sun. ". Q: What two elements primarily make up the sun? Choices: - oxygen and hydrogen - nitrogen and argon - calcium and helium - hydrogen and helium A:

Answer the following question given this paragraph: As the atoms approach one another, their electron clouds gradually begin to overlap. Now there are several interactions which begin to occur. One is that the single electrons that each hydrogen atom possesses begin to repel each other. This repulsive force would tend to make the potential energy of the system increase. However, the electron of each atom begins to be attracted to the nucleus of the other atom. This attractive force tends to make the potential energy of the system decrease. Q: As the atoms approach one another, their electron clouds gradually begin to do what? Choices: - magnetize - shrink - disappear - overlap A:
**Answer**
overlap

Answer the following question given this paragraph: Sound is a form of energy that travels in waves. Sound waves cannot travel through empty space, but they can travel through gases. Gases in the air allow us to hear most of the sounds in our world. Because of air, you can hear birds singing, horns tooting, and friends laughing. Without the atmosphere, the world would be a silent, eerie place. Q: What helps sound travel in waves? Choices: - molecules - speaker placements - temperatures - gases A:
