Thermodynamics

Thermodynamics = Deals with heat, work, and temperature, and their relation to energy, entropy, and the physical properties of matter and radiation Statistical mechanics = Explains the behavior of thermodynamics laws in terms of microscopic constituents Physical chemistry = Applies thermodynamics to the study of chemical systems Mechanical engineering = Applies thermodynamics to the design and analysis of power plants, engines, and refrigeration systems

Sadi Carnot = Believed that engine efficiency was the key that could help France win the Napoleonic Wars Lord Kelvin = Formulated a concise de = Desire to increase the efficiency of early steam engines

Entropy = A measure of the randomness or disorder in a system Laws of thermodynamics = Convey a quantitative description using measurable macroscopic physical quantities Microscopic constituents = Particles or entities at the smallest scale in a system Macroscopic physical quantities = Observable properties of a system that can be measured directly

<p>The four laws of thermodynamics are: 1) The law of conservation of energy, which states that energy cannot be created or destroyed, only transferred or converted from one form to another. 2) The second law of thermodynamics, which states that the entropy of an isolated system always increases over time. 3) The third law of thermodynamics, which states that it is impossible to reach absolute zero temperature. 4) The zeroth law of thermodynamics, which states that if two systems are in thermal equilibrium with a third system, they are in thermal equilibrium with each other.</p> Signup and view all the answers

<p>Thermodynamics and statistical mechanics are closely related. Thermodynamics provides a macroscopic description of the behavior of systems in terms of measurable quantities like heat and work, while statistical mechanics provides a microscopic explanation of the behavior of systems in terms of the motion and interactions of individual particles. Statistical mechanics allows for the derivation of thermodynamic properties from the microscopic behavior of the system.</p> Signup and view all the answers
