Thermodynamics — Syllabus & Topics
Topics covered in Thermodynamics for NEET-UG Physics.
Topics in Thermodynamics
Basic Concepts and Definitions
- Thermodynamic system: Collection of large number of atoms/molecules confined within boundaries
- Types of systems: Open (exchanges both energy and matter), Closed (exchanges only energy), Isolated (exchanges neither)
- Thermodynamic variables: P (pressure), V (volume), T (temperature), U (internal energy), n (number of moles)
Zeroth Law of Thermodynamics
- States thermal equilibrium relationship: If A and B are in thermal equilibrium with C, then A and B are in thermal equilibrium
- Establishes the concept of temperature as a measurable property
- Foundation for temperature measurement and thermometry
Heat, Internal Energy, and Work
- Heat (Q): Energy transfer due to temperature difference - path dependent
- Internal Energy (U): Total energy due to molecular motion and configuration - state function
- Work (W): Energy transfer due to force acting through displacement - path dependent
First Law of Thermodynamics
- Statement of energy conservation in thermodynamic processes
- Mathematical form: ΔQ = ΔU + ΔW
- Heat supplied equals increase in internal energy plus work done by system
