A ball bearing is to be dropped into each of these beakers. In which experiment will the ball travel the slowest?
选项
A、Experiment 1, because water at 20 degrees Fahrenheit is ice!
B、Experiment 2, because milk at 40 degrees Fahrenheit is ice!
C、Experiment 3, because oil at 60 degrees Fahrenheit is ice!
D、Experiment 4, because tar at 80 degrees Fahrenheit is ice!
答案
A
解析
华氏温度tF与摄氏温度t的换算关系为：tF=32+5t／9。根据这个关系可以确定冰点(0．00℃)为32．0。F，因此只有A项“20下的水”处于冰冻状态，球在容器A中运动最慢。
