CHEM 1002 Study Guide - Midterm Guide: Scots Guards, Intermolecular Force, Exothermic Process
Document Summary
Energy that flows from a warmer body to a colder body. It is impossible to completely convert heat into work without making other changes in the universe. Entropy of the universe is constantly increasing. Energy needed to initiate a chemical reaction. Ex: push a boulder down a hill. How much energy is dispersed in a given process. Chemical energy is a form of potential energy. Chemical process in which a fuel combines with oxygen to release energy and form products. Theory tries to provide the underlying cause but law does not. Breaking of larger molecules into smaller ones vehicles engine. Gasoline"s resistance to causing knocking due to premature ignition in a. Smallest dispersion forces are smaller in molecule (circle smaller than line) Down in intermolecular forces = lower bp. Oxygen containing molecules have less energy, so higher heat of combustion.
