Basic question regarding particle nature of matter
« on: February 08, 2019, 05:03:50 PM »
I came across this following question while poring over my textbook.

Predict the change in the motion of particles you would expect in the following if the temperature was increased
a) Solid
b) Liquid

I think if the temperature increases, solid or even liquid particles will receive more energy and therefore their motion will speed up. I'm not sure why there are two parts for this question. Aren't they supposed to be similar?
Thank you so much for helping! Since this is my first post, please pardon me if I accidentally violate any rules of the forum.

Depends on what you mean by "motion". Is translation from point to point a motion? Is vibration (oscillation) around a point a motion?

Temperature is directly proportional to kinetic energy of the particles in matter .I think this statement can help.

No. Only when the kinetic energies accessible to the current temperature are close enough. It would often be the case for metals at usual temperatures, but not for metal oxides for instance.

[..] Predict the change in the motion of particles you would expect in the following if the temperature was increased [..]

What shall "particles" be: molecules? Atoms?
