Question

Elaborate on the changes in molecular motion of particles as they change from solid to liquid to gas.
Question 16 options:


As the phase changes occur, the freedom of motion of the particles increases.


As the phase changes occur, the freedom of motion of the particles decreases.


As the phase changes occur, the freedom of motion of the particles compresses.


As the phase changes occur, the freedom of motion of the particles is constant.

Answer 1

This is the maths section btw. You might want to post this in the science section next time.
Okay..
So from Solid > liquid > gas they are less dense which also means??

Answer 2

As the phase changes occur, the freedom of motion of the particles increases.
