Question

3.4.2 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 if the heat source is removed.
a. the molecules will begin moving more quickly.
b. the molecules will begin moving more slowly.
c. the molecules will stop moving.
d. the motion will change very little.

Explanation:

The kinetic energy of molecules is related to temperature. When the heat source is removed, the temperature of water decreases. As temperature drops, the kinetic - energy of water molecules reduces, causing them to move more slowly.

Answer:

B. The molecules will begin moving more slowly.
