yes...
u can take example of water ...on freezing it or cooling it it's intermolecular spaces get reduced and finally it becomes ice...
which is a solid......

Yes every normal substances contract on cooling because the internal heat energy of the substance decreases on cooling.Hence there decreases motion of particle constituting the body.

The kinetic energy inside the body decreases.

The body becomes closely packed and hence becomes dense.

It also contracts as inter molecular space decreases.

Now here is an exception:

Water due to its anomalous expansion expands on cooling from 4C to 0C.

Thank you.

Hope it helps everyone.
