CHEM 1111 Study Guide - Midterm Guide: Endothermic Process, Heat Capacity, Ice Pack
Document Summary
Exam 2: chapter 5 outline, energy basics, calorimetry, enthalpy. Energy basics: thermochemistry- study of the heat absorbed released during chemical and physical changes, energy- capacity to supply heat or do work. 2 categories of energy: 1) potential- energy an object has because of its relative position, composition, or condition, 2) kinetic- the energy that an object possesses because of its motion. Calories is the amount of energy required to raise one gram of water by 1 c: heat, work, and energy is joule. Joule is the amount of energy used when a force of. If a substance gains thermal energy, final > initial; the value of q is positive. If a substance loses thermal energy, final < initial; the value of q is negative. If the reaction is exothermic, the heat produced is absorbed by the solution. Enthalpy: thermochemistry- science that deals with the relationships between work, heat, and other forms of energy.
