This mathematical model describes th 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 degrees to 100 degrees C. A. The movement of the molecules will gradually increase.

B. The movement of the molecules will gradually decrease.

C. The motion will change very little.

D. The molecules will stop moving.

A. The movement of the molecules will gradually increase.

Explanation:

The movement of the molecules in the water will increase due to increase in temperature because the water molecules absorb energy from heat.  Due to absorption of energy, kinetic energy is formed in the water molecules which are responsible for the motion of molecules so that's why the movement of molecules occurs due to increase in temperature. The molecule which is present at the bottom is the first one which absorb energy due to nearer to the energy source.
