21 multiple choice 2 points\nseth lay in bed, staring at the gray wall. another morning, he thought. another morning, and nothing has changed. these days, he woke in a daze, as if a thick fog surrounded his head. today, he had no desire to get out of bed at all. it was raining hard. he could hear the steady beating of rain on the rooftop, the slick rush of rain as it emptied from the drainpipe to the ground. he could hear his parents footsteps below. they were probably drinking coffee, eating the same breakfast of toast and jam. soon his father would pull his cap down against the rain and trudge outside, today like every other day of his life, to the barn to milk the cows. nothing ever changes, thought seth.\n“seth,” his mother called. “are you coming? arent you going to help your father?” slowly, very slowly, seth rose and dressed. he slid into his work boots, knowing that the ground would be muddy. as he trudged downstairs, he could see his whole future in front of him. he saw years of work boots and mud, years of feeding pigs and milking cows, years of following in his fathers footsteps. the steady rhythm of the rain droned into his head and heart. he wondered how long it would be before he left the farm for good.\nquestion: choose the word that best describes the tone of this passage?\nbewildered\npessimistic\ncynical\ndesperate\nclear my selection\n22 ordering 4 points\na liquid evaporates when it slowly changes into a gas without boiling. in a liquid state, the molecules of a substance are continually moving. the average speed at which the molecules move determines the temperature of the substance. as long as the temperature does not rise above the boiling point, then the substance remains in liquid form.\nhowever, the molecules of a liquid do not all move at exactly the same speed. the combination of their individual speeds creates an average speed that falls within the appropriate range. evaporation occurs when the fastest - moving molecules of a liquid rise to the surface. if they move fast enough, they are able to break away from the surface of the liquid and take on a gaseous form.\nas the fastest molecules escape and turn into vapor, the average speed of the molecules remaining in liquid form is lower. this lower average molecular speed means that the temperature of the liquid drops. therefore, when evaporation takes place, the liquid is cooled.\nthis cooling effect has been used for years in warm climates to create air - conditioning. many desert dwellers use evaporative cooling devices to keep their homes cool. less expensive to run than modern air - conditioning, evaporative coolers harness natures cooling process and put it to use!\nquestion: use the passage to put the steps of evaporation in order below.\nevaporation:\n1 molecules exist in a liquid state moving at different speeds.
