Document Summary
Energy is usually defined as the capacity to do work or transfer heat. Kinetic energy is the energy that results from motion o: m=mass of the object and u is the velocity. Thermal energy is the energy associated with the random motion of atoms and molecules. Potential energy is the energy possessed by an object by virtue of its position. An exothermic process is a process that releases thermal energy as heat o. Heat is the transfer of thermal energy between two bodies that are at o different temperatures. Thermochemistry is the study of heat in chemical reactions. Endothermic process is a process that absorbs thermal energy o. The si unit of energy is the joule (j) Calorie (cal) the amount energy it takes to raise one gram of water one degree. Thermodynamics is the scientific study of the interconversion of heat and other kinds of energy. Open system can exchange mass and energy with its surroundings.
