The three
states of matter are solid, liquid and gas phase. The solid has a more definite
shape and volume. The particles are locked into place. It cannot be further
compressed due to the bond that exists between the molecules. The kinetic
energy of the molecules is close to none because the molecules are so close and
so compact with each other. For liquids, it has a medium shape and volume. The
particles can move or slide past each other due to the small space available
for movement. It cannot be compressed further due to the repulsive forces that
acts between them. The kinetic energy is medium. For gases, it has no shape and
volume because the particles can move freely from one other. Their collisions
are rare due to the distance between them. The kinetic energy of the molecules
is high because there is room for movement. It can be compressed easily.
