Thermodynamic laws - Study guides, Class notes & Summaries

Define thermodynamics - Answer-The study of energy transformations that occur in a collection of matter. List the laws of thermodynamic and describe their relevance in the chemical reactions - Answer-First:-energy can be neither created nor destroyed-total energy in universe remains constant-however energy may be redistributed either within a system or between the system and its surroundings second:-physical and chemical processes proceed in such a way that the disorder of the universe incre...
