Publisher : Aayam. Thermodynamics is concerned with the work done by a system and the heat it exchanges with its surroundings. (iii). Thermodynamics:-It is the branch of physics which deals with process involving heat, work and internal energy.Thermodynamics is concerned with macroscopic behavior rather than microscopic behavior of the system. NCERT Solutions Class 11 Physics Chapter 12 Thermodynamics. The equilibrium temperature is only equal to the mean temperature when the thermal capacities of both the bodies are equal. Room temperature, T2 = 35°C = 35 + 273 = 308 K, Temperature inside the refrigerator, T1 = 8°C = 281 K, Since, the Coefficient of performance = T1T2−T1=281308−281=10.41\frac{T_{1}}{T_{2}-T_{1}}=\frac{281}{308-281}=10.41T2​−T1​T1​​=308−281281​=10.41, Therefore, the coefficient of performance of the refrigerator is 10.41.
