What You Learn in Chapter 4: Laws of Thermodynamics
This chapter introduces students to the four fundamental laws that govern thermodynamic processes. Key concepts include:
-
Zeroth Law of Thermodynamics – Concept of thermal equilibrium
-
First Law of Thermodynamics – Conservation of energy, internal energy, heat, and work
-
Second Law of Thermodynamics – Direction of heat flow, heat engines, entropy
-
Carnot engine and its efficiency
-
Reversible and irreversible processes
-
PV diagrams and thermodynamic processes
These laws are crucial not only in theoretical physics but also in engineering, environmental science, and real-life energy systems.
