State of Matter
a definite shape and volume with tightly packed particles and held in a fixed position
solid
matter can change from solid to liquid to gas due to changes in temperature and pressure affecting particle motion and interactions
phase changes
A definite volume but no definite shape allowing particles to move past each other
liquid
as temperature increases the what energy of particles increases causing them to move faster and exhibit different behavior in their respective states
kinetic energy
no definite shape or volume with articles moving freely
gas
what are the four types of matter?
solid liquid gas and plasma
similar to a gas but with changed particles that move independently and typically only exist at low presser
plasma
