Question

2.3.2 quiz: scientific models
this mathematical model describes the changes that occur in a sample of water as its temperature increases. use this model to predict what will happen to the motion of the molecules in a sample of water that is being heated from 50° to 100°c.
a. the motion will change very little.
b. the movement of the molecules will gradually decrease.
c. the molecules will stop moving.
d. the movement of the molecules will gradually increase.

Explanation:

As temperature increases, kinetic energy of molecules increases. In water, heating from 50°C to 100°C causes molecules to gain more kinetic energy and move more vigorously.

Answer:

D. The movement of the molecules will gradually increase.
