Wearing safety gloves and goggles, she is heating a pan of water on a hot plate. She observes water vapor beginning to rise from the surface of the water. As the water reaches 95°C, what can Hailey expect to observe soon? A. Drops of water dripping down the outside of the pan B. Bubbles of gas forming in the water C. The particles of water vibrating in place within the pan D. The particles of water moving together into a definite shape 4. Which statement best describes water at 30°C? A. It is a gas without a definite shape. B. It is a solid with a definite shape and volume. C. It is a liquid with a definite shape. D. It is a liquid with a definite volume. 5. On a warm day, a glass of ice water will form water droplets on the outside of the glass. What process causes this to happen? A. Condensation B. Evaporation C. Boiling D. Melting 6. Which of the following is true about a gas? A. It has a definite shape. B. It has a definite volume. C. It has a definite shape and volume. D. None of the above 7. The melting point of water is 0°C. Its boiling point is 100°C. The thermometers show the temperature of four samples of water. Which statement is true? A. Only sample B is solid. B. All four samples are liquid. C. Only samples A and C are liquid. D. None of these. 8. When you pull up on the handle of a bicycle pump, it takes particles of air into its cylinder. When you press down on the handle, it presses the air particles closer together, as shown below. A student wants to use a bicycle pump to change the shape and volume of a liquid. But, a note on the bicycle pump says that it works only on gases, not on solids or liquids. Why does the bicycle pump work only on gases? A. Only gases can change shape. B. Only gases have definite shape. C. Only gases can change volume. D. Only gases have definite volume. 9. What are the freezing and melting points of water on the Celsius scale? A. 100°C and 0°C B. 0°C and 100°C C. 0°C. D. 100°C III. Why can we use the melting point to help identify a material? ____________________________________________________ ____________________________________________________ ____________________________________________________ IV. What is the difference between evaporation and condensation? ____________________________________________________ ____________________________________________________ ____________________________________________________ ____________________________________________________
