change of phase

Styles mework #8 e: 04/18/2022 points apter 17: Change of Phase (Hint: Look in the textbook to find e answers to some of these questions) 1) Would evaporation be a cooling process if molecules of every speed had an equal chance to escape from the liquid surface? (2 points) 2) If the water level in a dish of water remains unchanged from one day to the next, can you conclude that no evaporation or condensation has occurred? (2 points) 3) Why does dew form on the surface of a cold soft-drink can? (2 points) 4) When H20 in the vapor phase condenses, is the surrounding air warmed or cooled? (2 points) 5) Suppose that 4 grams of boiling water is poured onto a cold surface and 1 gram rapidly evaporates. If evaporation takes 540 calories from the remaining 3 grams of water and no other heat transfer takes place, what will be the temperature of the remaining 3 grams? (3 points) 6) The heat of vaporization of ethyl alcohol (CHSCH2OH) is about 200 cal/g. If 2 kg of this fluid were allowed to vaporize in a refrigerator, show that 5 kg of ice would be formed from 0'c water. (3 points) a p
