CHEM 141 Final: Chapter 10 Textbook Review
Document Summary
Thermochemistry: the study of the relationships between chemistry and energy. Work: the result of force acting through a distance. Heat: the flow of energy caused by a temperature difference; the transfer of thermal energy. Temperature: a measure of the thermal energy within a sample of matter. Kinetic energy: the energy associated with the motion of an object. Thermal energy: the energy associated with the temperature of an object. Potential energy: the energy associated with the position or composition of an object. Chemical energy: the energy associated with the relative positions of electrons and nuclei in atoms and molecules, is also a form of potential energy. Joule ( j): the si unit of energy is the kg m2/s2 calorie (cal): the amount of energy required to raise the temperature of 1 g of water by 1. Calorie (cal): equivalent to 1000 lowercase c calories; the same as a kilo- calorie (kcal): 1 cal = 1 kcal = 1000 cal.
