Law of Thermodynamics Thermodynamics is the branch of physics that deals with the relationships between heat, work, and energy 🌡️. It's all about understanding how energy is converted from one form to another and how it affects the properties of matter. Some key concepts in thermodynamics include: Energy: The ability to do work or transfer heat. Heat: A form of energy transfer due to temperature difference. Work: Energy transfer through a force applied over a distance. Entropy: A measure of disorder or randomness in a system. The laws of thermodynamics are fundamental: 1. Zeroth Law: If A is in thermal equilibrium with B, and B is with C, then A is with C. 2. First Law: Energy can't be created or destroyed, only converted (conservation of energy). 3. Second Law: Entropy always increases over time in an isolated system. 4. Third Law: As temperature approaches absolute zero, entropy approaches a minimum.
