Explanation:

when things are hot they melt and when things get cold they freeze, think of regular water how it freezes and then melts.

electron microscopy and scanning tunneling microscopes gives us a greater understanding of atoms by being able to see the atom itself, and lets us see some atomic reactions.

explanation:

so what is the problem with your lab report and whats the subject of the lab report? i will you
