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

FAQs on NCERT Solutions for Class 11 Physics Chapter 12

Q.1: What are the three laws of thermodynamics?

Ans: Thermodynamics has identified three fundamental laws: the first law, the second law, and the third law.

Q.2: What is the importance of thermodynamics?

Ans: Thermodynamics is a vital branch of both physics and chemistry. It deals with energy, the conversion of energy between different forms, and the energy ability to do work.

Q.3: Where can I get NCERT Class 11 Physics Chapter 12 Solutions?

Ans: Students can get NCERT Class 11 Physics Chapter 12 Solutions at Embibe.

Q.4: What is the basic idea of NCERT Solutions for thermodynamics?

Ans: The study of energy, its transformations and its relation to matter defines the idea of thermodynamics. It clearly states that energy can change from one form to another, but the total energy remains constant.

Q.5: Are NCERT Solutions for Thermodynamics available for free?

Ans: NCERT Class 11 Physics Chapter 12 Solutions are available for free at Embibe.
