Chapter 10: Liquids and Solids

1. Which statement accurately depicts what happens to water on the molecular level in a tea pot when it begins to boil? (Outcome # 9) (DOK 3)
2. The molecules begin to move farther apart decreasing their intermolecular forces and they escape the liquid state to enter the gas state.
3. The molecules begin to move closer together overcoming their intermolecular forces which holds them together and they escape the liquid state to enter the gas state.

46. water
47. methanol
48. ethyl ether
49. Based off of the principles of intermolecular forces, which liquid has the lowest vapor pressure? (Outcome # 8) (DOK 2) (Paired item 1)

53. If it takes you 10 min. to boil an egg to perfection at sea level, how long would it take to boil an egg to your taste in the Carpathian Mountains at elevations of 8,500 ft? (Outcome # 8) (DOK 3)
54. The boiling point of water in the Carpathian Mountains is less than 100 °C because of lower atmospheric pressure which results in reduced intermolecular forces, so it would take a longer time to boil the egg.
55. The boiling point of water in the Carpathian Mountains is greater than 100 °C because of lower atmospheric pressure which results in increased intermolecular forces, so it would take less time to boil the egg.
56. The boiling point of water is always 100 °C regardless of elevation so it would take the same amount of time to boil the egg.
