1) A student observed liquid wax dripping down the side of a burning candle. After putting out the candle’s flame, the student left the room. Several hours later the student observed that there was no longer any liquid on the side of the candle. Which statement explains what most likely happened to the liquid wax?  a) The heat given off by the flame caused the candle wax to evaporate. b) The liquid wax changed back into a solid as it cooled. c) The liquid wax condensed and was absorbed by the candle. d) None of the above 2)  Students observe a glass of ice and water. The glass is dry on the outside. After ten minutes students see drops of water on the outside of the glass. Which statement best explains the students’ observations? a) The water vapor in the air changes to a liquid when it touches the cold glass. b) The cold water inside the glass rises and then slides down the outside of the glass. c) The ice in the glass melted and caused the water to overflow the glass. d) The water moved to the outside surface through tiny holes in the glass. 3) A group of students is performing an investigation to measure how much liquid water is produced from a 10 L sample of snow. What must occur in order for the students to perform this investigation? a) The sample must be kept in a freezer. b) The temperature of the sample must change. c) The investigation must be performed outside. d) The physical state of the sample must remain the same. 4) Some students put two ice cubes on separate plates. One ice cube had a mass of 80 grams. The other had a mass of 40 grams. Which result would be the same for both ice cubes in this investigation? a) The time it took each ice cube to melt completely b) The temperature at which each ice cube melted c) The amount of liquid produced on each plate d) The total volume of each ice cube 5) Which statement BEST describes what happens as water changes from one state to another? a) As water is cooled, it freezes and changes from a solid to a liquid. b) As water is cooled, it condenses and changes from a gas to a liquid. c) As water is heated, it evaporates and changes from a liquid to a solid. d) As water is heated, it melts and changes from a gas to a solid. 6) If heat is added to a liquid, what will most likely happen? a) The temperature of the liquid will decrease and it will form a solid. b) The temperature of the liquid will increase and it form a solid. c) The temperature of the liquid will decrease and it will form a gas. d) The temperature of the of the liquid will increase and it will form a gas. 7) To change the state of matter you must . . . a) Add heat b) Remove heat c) Add or remove heat d) Keep the temperature the same. 8) What process is a change from a liquid to a gas? a) Condensation b) Melting c) Freeezing d) Evaporation 9) When a solid changes to a liquid, what process occurs? a) Melting b) Freezing c) Evaporation d) Condensation 10) Which two states of matter take the shape of their containers? a) Solids and Liquids b) Liquids and Gases c) Solids and Gases 11) Which two states of matter have a definite volume? a) Solids and Liquids b) Liquids and Gases c) Solids and Gasess 12) Which state of matter has no definite shape and no definite volume? a) Solid b) Liquid c) Gas
