16. T

17. F, sublimation

18. T

19. F, freezing

20. F, amorphous

21. viscosity

22. pressure, temperature

23. decreases

24. thermal

25. Temperature

26. crystalline

27. Boiling

28. thermal

29. melting

30. State A. The particles are not in a fixed pattern as particles in a solid are; the particles can move around one another, but they remain quite close together.

31. States A and C, because the particles are free to move

32. State C, because heating increases the energy of the particles. They would move faster and begin to move farther apart.

33. The figure shows that the volume and pressure of a gas are related, and that as the volume of a gas decreases, its pressure increases.

34. If the cylinder was heated, the temperature of the gas would increase. With the plunger held steady, the volume of the gas would remain constant. Under those conditions (increasing temperature and constant volume), the pressure of the gas would increase.

35. Boyle’s law. Boyle’s law states that when the pressure of a gas increases at constant temperature, its volume decreases; when the pressure of a gas decreases, its volume increases.
