NAGALAND Class 11-science Physics Thermodynamics
First Law of Thermodynamics
The 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 Processes
1. 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 Engines
Study of principle of working of Heat engines. Study various stages of Carnot cycle and calculate Efficiency of an ideal Carnot engineSecond Law of Thermodynamics
State various forms of second law of thermodynamics. Discuss the working principle of Refrigerators and Heat pumps
