2 6. If you open a bottle of perfume, after a period of time, the people on the opposite side of the room will be able to smell it due to the process of STAs3 a. condensation. b. evaporation. c. sublimation. d. vapor pressure. 7. A drop of vinegar will flow and spread out but a drop of vegetable oil will form a bead. This is evidence that STAs1 a. vegetable oil has a lower surface tension and lower viscosity than vinegar. b. vinegar has a lower surface tension and lower viscosity than vegetable oil. c. vegetable oil has a lower surface tension and higher viscosity than vinegar. d. vinegar has a lower surface tension and higher viscosity than vegetable oil. 8.

In order for carbon dioxide gas to enter the air from dry ice, the dry ice must STAs3 a. gain energy. b. boil. c. increase in pressure. d. undergo an exothermic change. 11. Which of the following statements is NOT true of all different types of matter? STAs1 a. They are made up of atoms and molecules. b. The particles that make them up are always in motion. c. They are made up of extremely small particles. d. The particles that make them up move at the same speed. Holt Science and Technology 38 States of Matter

3 12.

The reverse of condensation is STAs3 a. boiling. c. freezing. b. evaporation. d. sublimation. MATCHING Match the correct description with the correct term. Write the letter in the space provided. 14. It can be determined by measuring the speed of molecules. STAs2 15. This happens when tomato soup boils. STAs3 16. Ice, water, and steam are all examples. STAs1 17. This is a state of matter in which atoms and molecules are close together but can slide past each other. STAs1 18. It has no definite volume. STAs1 19. It may be either crystalline or amorphous. STAs1 a. states of matter b. viscosity c. solid d. liquid e. surface tension f. gas g. temperature h. volume i. pressure j. change of state 20.

As the balloon is twisted and the volume of the space in which the air is contained is reduced, the pressure will increase. 15. The temperature of the water will remain the same. 16. If energy is added, the ice will melt, and if energy is removed, the water will freeze. 17. The boiling point of liquids decreases as atmospheric pressure decreases. At higher elevations, atmospheric pressure is reduced, so the boiling point of water will be lower than at sea level. This means that pasta boiled in Denver will cook at a lower temperature than pasta boiled in Louisiana. Pasta will have to cook longer in Denver. 18. Dry ice changes directly from a solid to a gas, producing a smoke like effect. Pouring water over the dry ice causes the carbon dioxide to sublime quickly. As a result, it turns to gas more quickly, producing a more dramatic smoke like effect. 19. The colder the weather is, the more helium will need to be pumped into the balloons for them to inflate to the desired level. This is because the colder the temperature, the slower the particles of gas move and the slower they hit the inside of the balloon. Thus, the colder it is, the lower the pressure. So, if it is cold out, more particles of gas will be needed in order to have the same level of pressure as with fewer particles on a warmer day. 20. A, gas; C, liquid; E, solid 21.
