CBSE Class 11-science Physics Thermodynamics
First Law of ThermodynamicsThe nature of heat and its relationship to mechanical work was studied by Joule.
The first law of thermodynamics is based on the principle of conservation of energy.
Zeroth law of thermodynamics states that two systems in thermal equilibrium with a third system, are in thermal equilibrium with each other.
Thermodynamic Processes1. For an ideal gas: Cp andgt; Cv andandnbsp; (Cp andndash;Cv ) = R
2. Adiabatic process: Q = 0
3. Isochoric process : W = 0
4. Isobaric process: W = pandDelta;V
5. Isothermal process is a process for which temperature remains constant.
Heat EnginesStudy of principle of working of Heat engines. Study various stages of Carnot cycle and calculate Efficiency of an ideal Carnot engine
Second Law of ThermodynamicsState various forms of second law of thermodynamics. Discuss the working principle of Refrigerators and Heat pumps
