Document Summary
Van der waals bonds: weak electrostatic bonding, hydrogen bonds, eo = disassociation energy required to break a bond. Thermodynamics: energy changes, use chemistry of minerals and thermodynamics to predict what type of mineral would be stable at different depths in the crust, system- part of the universe being studied, surroundings: material around the system. Open, closed, isolated: properties of a system. Independent of the amount of matter present (ex. Dependent on the amount of matter present (ex. Dividing two extensive variables produces an intensive variable (ex. Measure of kinetic energy of the atoms in a system. 0k = no kinetic energy = -273. 15 c. 273. 15 k is the melting point of water: laws of thermodynamics. When two objects are separately in thermodynamic equilibrium with a third object, they are also in equilibrium with each other. (heat transfer. Heat transfer = not in thermal equilib: transferred from warmer object to cooler, heat capacity of a substance is dependent on temperature.
