THERMODYNAMICS

• Thermodynamics - states that any spontaneously occurring process in the entropy ( DELTA S ) of the universe.
• Entropy - a measure of the amount of energy which is unavailable to do work, measurement of disorder in a system.
• Rudolf Clausius - a German physicist who coined the term "entropy" in 1865.
• Rudolf Clausius - Father of the second law of thermodynamics.
• Rudolf Clausius - he describes how to measure the entropy of an isolated system in thermodynamical equilibrium with its part
• As the temperature increases the entropy also increases
• Entropy increases as one goes from solid to a liquid to gas
• Entropy increases as the number of particles (molecules) increases in system
• Entropy increases if a solid or liquid dissolved in solvent
• Entropy increases - positive sign
• Entropy decreases -- negative sign
