### NCERT Solutions for Class 11 Physics Chapter 12: Points to Remember

Some of the points to remember from Class 11 Physics Chapter 12 are as follows:

• Zeroth law of thermodynamics: According to this law, systems in thermal equilibrium have the same temperature.
• First law of thermodynamics:  dQ=dU+dW
• Thermal resistance to conduction: R = L/KA
• Newton’s law of cooling: dθ/dt = (θ – θ0)
• Temperature scales: F= 32 +(9/5)C or K = C + 273.16
• Linear Expansion is L = L0(1+αΔT)
• Volume Expansion is V = V0(1+yΔT)
• First law of thermodynamics: ∆Q = ∆U + ∆W
• Ideal gas equation: pV = nRT
• Efficiency of the heat engine: η = work done by the engine/heat supplied to it = Q1 − Q2/Q1
• Relation between Cp and Cv: Cp − Cv = R
