A student bounces 3 balls and measures the bounce height of each ball. Each ball is identical except for the temperature: A is 70˚C, B is 25 ˚C, and C is 0 ˚C. Each ball was dropped from 70cm height. The ball at 70 ˚C bounced the highest at 40cm, the 25 ˚C ball bounced 10cm, and the 0 ˚C bounced 2cm. What was the purpose of this experiment?

Question 7 options:

to determine the ratio of bunce height and drop height


to determine how elastic balls are when they are dropped from 70 cm


to determine how temperature affects bounce height


to determine how drop height affects bounce height
