  6. Time’s up kiddo’s!!!!!!!!

  7. Correct Answer: B — freezingExplanation: Freezing is the phase change from a liquid to a solid. Different materials freeze at different temperatures. Water freezes at 0°C. Molten lava has a much higher freezing point, about 1000°C! • Molten lava pours from a volcano in Hawaii. After a few hours, the liquid lava hardens into a shiny gray rock. Which phase change has taken place?A. melting • B. freezing • C. boiling • D. condensation

  8. Correct Answer: B — Image 1 is liquid, image 2 is solid, and image 3 is gas. Explanation: In a liquid, molecules are packed together and move freely. Molecules in a liquid will not show a pattern. Image 1 shows a liquid. In a solid, molecules are held together in a rigid structure. The molecules in a solid will often have a pattern. Image 2 shows a solid. In a gas, molecules move freely and are spaced far apart. Image 3 is a gas. • Correct Answer: D — condensation Explanation: The water on the bottle actually came from the air around the bottle. Air contains a small amount of water vapor. When this air hits a cold surface, the water vapor cools and condenses on the bottle.
