Document Summary
Smallest unit from which entire pattern can be made. Coordination numbers = number of nearest neighbors surrounding particle. Simple cubic 52% efficiency, coordination number = 6, atoms/unit cell. Body centered cubic 68%, coordination number = 8, atoms/unit cell = 2 ( * 8 + 1) Face centered cubic 74%, coordination number = 12, atoms/unit cell = 4 ( * 8 + * 6) Phase diagrams tp = triple point, where all phases meet. Critical point : where l/g boundary ends. Critical temperature : highest temperature a liquid can exist at regardless of pressure, get too much ke to be held. Critical pressure : highest pressure gas can exist regardless of temp. Supercritical fluid : single dense fluid existing past critical point, like gas and fills container, density like fluid. Solvent = substance present in greatest quantity, agent. Percent by mass = mass solute / mass solution. Mole fraction = moles of solute b / total moles of solution.
