HEAT and THERMODYNAMICSTemperature:-
1. The concept of thermal equilibrium- Zeroth Law of Termodynamics,- temperature scales and empirical temperature, - measurement of temperature and types of termometers.
2. Quantity of heat: - Specific heat, - latent heat of fusion and vaporisation, - measurements of heat, Phase changes.
3. Transfer of heat: - heat conduction and determination of heat conductivity for good conductors
and insulators.
4. Quantitative analysis and linear expansion coefficient - (a), surface expansion coefficient- (b) and volume expansion coefficient.
5. Radiation:- - Thermal radiation as a form of energy, - black body radiation, Stefan’ Law.
Thermodynamics:- 1. Gas Laws; Ideal Gas Equations;
2. Kinetic theory of gases;
3. Work done by Gas. - Gas processes; Isothermal, Isobaric, Isochoric and Adiabatic Processes
4. First Law of Thermodynamics; Q = U + W
5. Heat engine and Carnot engine - Heat Pump and refridgerator
6. Second Law of Thermodynamics; - Entropy and order
