Chemistry branches to all other fields of science. Anthing that has mass and occupies volume. Energy plays a central role in properties of the states of matter and in changes. Energy: the capacity to do work, motion of an object, energy is associated with changes b/n states of matter, 2 types, kinetic energy. A rock has potential to move at a later time due to the effect of gravity acting on it. Kinetic forces dominate intermolecular forces of attraction. Their motion draws them too far apart to interact. Intermolecular forces play little to no role: liquid. Attractive forces (intermolecular forces) dominate the effect of kinetic energy: solids. Intermolecular forces are storng enough to prevent molecules form moving past each other.
