Changing States of Matter
Molecules can move from one physical state to another (phase change) and not change their atomic structure. Oxygen (O2) gas has the same chemical properties as liquid oxygen. ... Although its physical state may change because of different amounts of energy, its atomic structure remains the same.
The state or phase of a given set of matter can change depending on pressure and temperature conditions, transitioning to other phases as these conditions change to favor their existence; for example, solid transitions to liquid with an increase in temperature. Near absolute zero, a substance exists as a solid.The state or phase of a given set of matter can change depending on pressure and temperature conditions, transitioning to other phases as these conditions change to favor their existence; for example, solid transitions to liquid with an increase in temperature.
