7. Steam from a pot of boiling water touches a cold kitchen window. Which of these explains what happens to the steam and why? AThe steam changes from a gas to a liquid because the steam gains heat when it touches the window. BThe steam remains a gas because the steam loses heat when it touches the window. CThe steam changes from a gas to a solid because the steam gains heat when it touches the window. DThe steam changes from a gas to a liquid because the steam loses heat when it touches the window.

8. What happens to the state of a candle’s wax when the candle is burning? Burning a candle will… change it from a __________ to a ___________. Some of the burning candle will change to a _________. liquid gas solid

10. Olive oil is a liquid at room temperature. A student pours liquid olive oil from a frying pan into a jar and places the jar in a freezer. The next morning, the student observes that the olive oil in the jar has hardened in the freezer. What conclusion about the olive oil’s physical property can be drawn from this experiment? AOlive oil’s state of matter changes from a liquid to a solid when placed in below freezing temperatures. BOlive oil can be used to conduct electricity in the freezer. COlive oil’s buoyancy does not change when it freezes. DOlive oil and water have the same density when they are both frozen.

18. Which of the following will most likely cause an ice cube to melt? ACovering the ice cube with aluminum foil. BAdding heat to the ice cube. CPutting the ice cube in a dark place. DReturning the ice cube to the freezer.

19. Which of the following best explains how a freezer turns liquid water into solid ice? AAir in the freezer blows on the water. BElectric current makes a magnetic field. CFreon gas is added to the water. DHeat is removed from the water.

20. What happens when ice cream melts? ARemoving heat energy makes a gas change into a liquid. BAdding heat energy makes a solid change into a liquid. CRemoving heat energy makes a liquid change into a solid. DAdding heat energy makes a liquid change into a gas.

21. On a hot summer day in Texas, water droplets often form on the outside of a cold glass of water. Where does this water come from? AWater vapor in the air changes to a liquid when it loses heat on the cold glass. BA chemical reaction occurs between the glass and the water as it heats up. CAs the ice melts, it makes more water that goes to the outside of the glass. DWater leaks out through very tiny holes in the glass.

22. If you leave a glass of water outside in the summer, what will most likely happen to the water in the glass? AThe water will turn to ice as the wind blows over it. BSunlight will add gases to the water, so its volume will increase. CThe level of water will rise as the water vapor condenses inside the glass. DThe water level will decrease as heat causes the water to evaporate.
