Document Summary

Define a solid, liquid, gas, adsorbate, and plasma. Solid: removal of more energy from liquid state, intra-molecular forces dominate; molecules remain in a fixed position but continue to vibrate; resistant to change in shape/ volume. Liquid: strength of attraction between molecules in stronger than the kinetic energy of moving molecules; does not strongly resist forces that act to change its shape. Gas: molecules with high levels of kinetic energy. Adsorbate: gases or liquids that are loosely attached to the molecules of liquids/solids; exists only at the microscopic level with characteristics between liquid and vapor. Plasma: compound with its atoms stripped of their electrons, typically by very high temperatures. Plastic: stress-strain relationship is proportional upon loading/unloading is non-proportional; corresponds with the breaking of atomic bonds between original neighbors and remaking of bonds with new neighbors; upon unloading, atoms do not return to their original position. Dependence of the material properties based on its history.
