Document Summary

Boiling points and evaporation: boiling: turning liquid into gas, breaking all interactions between molecules. Molecules with high kinetic energies break away from the liquid. Functional groups: group of atoms that have a typical behavior. Combustion reactions happen in the gas phase because it is the reaction of fuel with oxygen to release energy in the form of heat and light. Thermochemistry: law of conservation of energy: energy is neither created nor destroyed. Amount of energy is constant: efficiency: % of energy converted from one type to another. Exothermic: releases energy (forming bonds) e < 0. Thermoneutral: chemical reaction with 0 net change. Activation energy: chemical reaction that must be activated. Calorimetry: measuring changes in state variables of a body for the purpose of deriving the heat transfer associated with changes in its state. Catalysts: speeds up a chemical reaction, doesn"t change products or reactants, decreases activation energy.
