CHEM 0110 Chapter Notes - Chapter 6: State Function, Degree Symbol, Thermodynamic System
Document Summary
Thermochemistry: science of the relationship between heat and other forms of energy. Quanitity of heat absorbed and givenoff by chemical reactions. Kinetic e: the energy associated with an object by virtue of its motion. Joule (j): unit of energy: (kg x m^2/s^2) B/c joule is such a small unit of e, watt is used for electric e. 100-watt bulb uses 100 joules of. E per second. calorie: a non-si unit of e commonly used by chemists, originally defined as the amount of e required to raise the temperature of one gram of water by one degree celsius. Potential e: energy an object has by virtue of its position in a field of force. Note: only differences in potential e are important for study. Once the object starts moving, the potential e decreases, the ek increases. Internal e (u): the sum of the ek and ep of the particles making up a substance.
