AP Chemistry Chapter 6 Reading Assignment

Summarize the introduction Energy Law of conservation of energy Potential energy Kinetic energy Look at figure 6.1. Ball A stopped moving…what happened to its energy? We know energy must be conserved… Heat Work What is “the pathway”? State function or state property. Give an example. The book uses distance traveled and change in elevation to discuss the idea of a state function. Explain which is a state function and which is not.

NAME:

System Surroundings Exothermic Endothermic Friend 1 tells you that the freezing of water is exothermic. Friend 2 says that this can’t be true because exothermic implies “hot” and ice is cold. If the process of water freezing exothermic? Is so, explain it so your friends can understand. If not, explain why not. What happens to the energy lost by a system? What happens to the chemical energy stored in chemical bonds during a reaction? Thermodynamics First law of thermodynamics Internal energy Calculate the ∆E for a system undergoing an endothermic process in which 15.6 kJ of heat flows and where 1.4 kJ of work is done on the system.
