Matter undergoes transformations, so chemistry studies both matter and its changes.
📌 The three states of matter are solid, liquid, and gaseous states, and temperature and pressure influence which state matter adopts.
A solid has a defined shape and volume and is ordered and rigid.
A liquid has a volume, takes the shape of its container, is disordered, and is incompressible.
A gas has neither a defined shape nor a defined volume, occupies all available space, and is disordered.
Physical changes of state include:
1. What does chemistry study?
2. Which statement best describes matter?
3. What determines which state of matter a substance adopts under given conditions?
