States Of Matter

Three Main States of matter

Particles in a solid are close together solids A state of matter where particles are tightly bound. Solids maintain volume and shape. Particles in a solid are close together The particles are constantly vibrating

Particles in a liquid are close together but loose liquids State of matter where particles are loosely bound. Liquids have a set volume but can change shape. Particles in a liquid are close together but loose The particles are constantly vibrating and shifting around

Particles in a gas are far apart Gases State of matter where particles are unbound. Gases can change shape and volume. Particles in a gas are far apart The particles are constantly bouncing around

Changing states

Changing States using temperature Adding thermal energy increases the kinetic energy of the molecules Add Heat (energy) Solids  liquid  Gas Remove Heat (energy) Gas liquid  solids

Changing states using pressure Increasing the pressure presses the molecules closer together Increase pressure Gas  liquid  solid Decrease pressure Solid  Liquid  Gas
