Answer:

As we know on heating the particles of matter start moving and temperature breaks the force of attraction of particles and by this reason substance started expanding. And in the other hand when we decrease the temperature of substances it started shrinking because the kinetic energy of particles become low.

So, in sense of mercury of thermometer-

Mercury starts expanding or rise on high temperature and its level came down after keeping in a glass of water because due to decreased in temperature as compared to previous temperature.
