Chapter 8: Heat and Thermodynamics explores the fundamental principles governing energy transfer, thermal properties of matter, and the laws that dictate energy transformations. The chapter begins with thermal expansion (linear: ΔL = αL₀ΔT; volumetric: ΔV = βV₀ΔT) and heat transfer mechanisms (conduction, convection, radiation).
It introduces specific heat capacity (c = Q/mΔT) and latent heat (Q = mL) for phase changes.The kinetic theory of gases connects microscopic particle motion to macroscopic properties, deriving gas laws (Boyle's, Charles') and pressure-temperature relationships. The core focuses on:
- First Law of Thermodynamics (ΔU = Q - W): Energy conservation in systems
- Second Law: Entropy (S) always increases in irreversible processes
- Thermodynamic processes: Isothermal, adiabatic, isobaric, and isochoric
Ch-08: Heat and Thermodynamics - MCQs
The document contains multiple choice questions from Chapter 8 on Heat and Thermodynamics for Class 11 Physics. It covers various concepts including internal energy, gas laws, thermodynamic processes, and the first law of thermodynamics. The questions test knowledge on topics such as temperature, pressure, entropy, and the efficiency of heat engines.
