Document Summary
Chapter 6 energy relationships in chemical reations. 6. 1 the nature of energy and types of energy. Energy is the capacity to do work. Radiant energy or solar energy, comes from the sun. Thermal energy is the energy associated with the random motion of atoms and molecules. Chemical energy is the energy stored in the structural units of chemical substances. Where the quantity of energy is determined by type and arrangement of constituent atoms. Potential energy is the energy available by virtue of an object"s position. Kinetic energy is the energy of motion. Law of conservation of energy the total energy in the universe is assumed constant. When one form of energy disappears, some other form of energy appears (of equal magnitude) Heat is the transfer of thermal energy, although heat implies the transfer of energy, we usually talk about heat flow, heat absorbed or heat released. Thermochemistry is the study of heat change in chemical reactions.
