THERMODYNAMICS Part 2 | ENTHALPY | Best Revision | NEET | JEE

Thermodynamics is the branch of physics that deals with heat and its relation to work, temperature, and energy. Essentially, it describes how energy moves and transforms within a system.  The field is governed by four fundamental laws:  1. Zeroth Law: Establishes the concept of temperature, stating that if two systems are each in thermal equilibrium with a third system, they are also in thermal equilibrium with each other. This is why a thermometer works!  2. First Law: This is the principle of conservation of energy. It states that energy cannot be created or destroyed, only transformed from one form to another (e.g., from chemical energy in fuel to heat and mechanical work in an engine).  3. Second Law: Introduces the concept of entropy, which is a measure of disorder. It states that the total entropy of an isolated system can only increase over time. This law explains why heat naturally flows from hot objects to cold objects and why no engine can be 100% efficient.   4. Third Law: States that as the temperature of a system approaches absolute zero (0\text{ K} or -273.15\text{ °C}), the entropy of the system approaches a minimum or zero value. #chemistry #education #physics #jee #neet #neetmotivation #bestapproach #bestlecture #bestrevision #viral #viralvideo #trending #youtube #thermodynamics #thermochemistry #exam #conceptneet #conceptneetacademy #conceptneetdigital
