__Laws of Thermodynamics __ Thermodynamics is the study of the inter-relation between heat, work and internal energy of a system. These three laws are, • First Law of Thermodynamics: – AKA:Law of Conservation of Energy – suggests that energy can be transferred from one system to another in many forms – it cannot be created or destroyed • total amount of energy available in the Universe is constant – relationship between energy and matter • E=mc 2  – energy and matter are interchangeable • Second Law of Thermodynamics: – Heat cannot be transfer from a colder to a hotter body – predicts that the entropy of an isolated system always increases with time • measure of the disorder or randomness of energy and matter in a system • <span style="color: black; font-family: Calibri; font-size: 16pt; font-style: italic; font-weight: bold; language: en-US; mso-ascii-font-family: Calibri; mso-bidi-font-family: +mn-cs; mso-color-index: 1; mso-fareast-font-family: +mn-ea; mso-font-kerning: 12.0pt;">Third Law of Thermodynamics: – <span style="color: black; font-family: Calibri; font-size: 16pt; language: en-US; mso-ascii-font-family: Calibri; mso-bidi-font-family: +mn-cs; mso-color-index: 1; mso-fareast-font-family: +mn-ea; mso-font-kerning: 12.0pt;">if all the thermal motion of molecules (kinetic energy) were removedstate of absolute zero • <span style="color: black; font-family: Calibri; font-size: 16pt; language: en-US; mso-ascii-font-family: Calibri; mso-bidi-font-family: +mn-cs; mso-color-index: 1; mso-fareast-font-family: +mn-ea; mso-font-kerning: 12.0pt;">Absolute Zero = 0 Kelvins = -273.15° Celsius – <span style="color: black; font-family: Calibri; font-size: 16pt; language: en-US; mso-ascii-font-family: Calibri; mso-bidi-font-family: +mn-cs; mso-color-index: 1; mso-fareast-font-family: +mn-ea; mso-font-kerning: 12.0pt;">The Universe will attain absolute zero when all energy and matter is randomly distributed across space <span style="color: black; font-family: Calibri; font-size: 16pt; font-style: italic; language: en-US; mso-ascii-font-family: Calibri; mso-bidi-font-family: +mn-cs; mso-color-index: 1; mso-fareast-font-family: +mn-ea; mso-font-kerning: 12.0pt;">

 * Environmental Impact: **
 * Wind Energy- **
 * absolutely no air pollution
 * windmills take up a lot of land space
 * birds are electrocuted/collide with the machines created to produce wind energy
 * extremely noisy
 * absolutely no air pollution
 * health/safety hazards for workers that come into contact with them
 * solar power plants take up a lot of land space
 * produces air and water pollution
 * need a safe disposal place for hazardous waste and land subsidence
 * geothermal power plants require a large amount of water
 * creates large amounts of noxious fumes
