Question

How does the molecular motion of a sustance change when it goes from liquid to solid?

A) The molecules lose energy, and their relative motion decreases
B) The molecules gain energy,and their relative motion decreases
C)The molecules gain energy, and their relative motion increases
D) The molecules lose energy, and their relative motion increases

Answer 1

Answer:

B) The molecules gain energy, and their relative motion decreases

Answer 2

The change in the molecular motion should be option B.

Change in molecular motion:

The molecular motion refers to the movement of constituent particles or molecules in a specific direction. It should be impacted by heat and temperature. When there is the transformation from liquid to solid so the change in the molecular motion of the substance should be that the molecular gained the energy and there should be a decrease in the relative motion.
