Unformatted text preview: II. 6.2 Conservation of Energy a. First Law of Thermodynamics or Law of Conservation of Energy- Energy is neither created nor destroyed in ordinary chemical reactions and physical changes- the total amount of energy in the universe is constant. i. When a force acts on an object and moves the object, the change in the objects kinetic energy is equal to the work done on the object. ii. Work is also requited to increase the potential energy of an object. iii. The work done on an object corresponds to the quantity of energy transferred to that object; that is doing work (or working) on an object is a process that transfers energy to an object. b. Energy, Temperature, and Heating i. Heat- refers to the energy transfer process that happens where ever two samples of matter at different temperatures are brought into contact. Energy always transfers from the hotter to the cooler sample until both are the same temperature...
