Document Summary

Thermodynamics: the study of energy and its transformations. Thermochemistry: chemical reactions and energy changes that involve heat. Energy: the capacity to do work or transfer heat. Work: the energy used to cause an object to move against a force. Heat: the energy used to cause the temperature of an object to increase. Potential energy: stored energy relative to its position. Electrostatic potential energy: comes from interactions between charged particles. Proportional to the electrical charges on the two interacting objects multiplied by the proportionality constant k and inversely proportional to the distance separating them. Calorie: 1 cal=4. 184 j ; 1 cal = 1000 cal = 1kcal. Open means matter and energy can be exchanged between the system and surroundings. Closed system means energy but not matter can be exchanged. Isolated system means neither energy nor matter can be exchanged. Force (f): any push or pull on an object w=f*d.
