Weekend Reading Concepts

Weekend Reading Concepts C.2-C.4

By Kelly Moran

In this past weekend's reading, I learned many new terms and concepts. Potential energy is energy of the position or condition (for example a bolder on top of a hill) and kinetic energy is energy related to the motion. Chemical energy is another form of potential energy and is stored in chemical compounds. The reaction in a chemical reaction releases thermal energy. Thermal energy is the part of total potential energy and kinetic energy of an object and is heat releasing energy. In a chemical reaction, the bond-breaking part is an energy requiring process called an endothermic change. The formation of chemical bonds is an energy releasing process called an exothermic change. The Law of conservation of energy states that energy is neither created nor destroyed in any mechanical, physical, or chemical process. The quantity of thermal energy given off when a certain amount of a substance burns is called heat of combustion. If the amount of substance burned is one mole, the quantity of thermal energy involved is called the molar heat of combustion. These are all the main concepts and terms from last weekend's reading!
