Question

You place a glass of water in the freezer. Hours later the glass of water has frozen solid. What happened to the particles in the glass?

A. They started to move freely.
B. They slowed down and packed together.
C. They moved faster and packed together.
D. They slowed down and moved freely.

Answer 1

the answer is b
the slow down because of the change of form into solid and they pack together to form the solid

Answer 2

The answer is B

Step-by-step explanation:

The answer to this question is based on the molecular kinetic theory. The more you diminish the temperature, the slower the kinetic energy of molecules (i.e their movement) will be. Therefore, if the particles aren't allowed to move freely, they'll package themselves and the mean distance between two particles will be fixed and the shortest you'd be able to find.
