How does decreasing the temperature of a solid affect the motion of the particles in the solid?
A. The particles become locked in place and vibrate.
B. The particles vibrate more slowly.
C. The particles slide past each other more quickly.
D. The particles stop moving.

B

Explanation:

If matter is heated and thus its temperature rises more and more, it can be seen that the particles contained in it move ever faster – be it the relatively free movement of the particles in gases or the oscillation around a rest position in solids. The temperature of a substance can therefore be regarded as a measure of the velocity of the particles it contains. With a higher temperature and thus higher particle velocity, the kinetic energy of the particles also increases.
