NCERT Solutions for Class 11 Chemistry Chapter 6 Thermodynamics

Thermodynamics is the branch of science which deals with the transfer of energy or changes in energy in physical or chemical processes. This is an important chapter for class 11th students because some concepts of this chapter we will also apply in the next chapter which is equilibrium and also some in the 12th class chapters like chemical kinetics etc. In this chapter, there are 22 questions in the exercise. The NCERT Solutions for Class 11 Chemistry Chapter 6 Thermodynamics are prepared and solved by our subject experts. These NCERT solutions of class 11 help students in the preparation of class 11 final examination as well as in the competitive exams like JEE Mains, NEET, etc.

Thermodynamics enables us to study energy changes quantitatively and to make useful predictions. For these, we divide the universe into the system and the surroundings. In thermodynamics, the system is the part of the universe where observations are made and the remaining universe constitutes surroundings. After completing NCERT Class 11 Chemistry Chapter 6 Thermodynamics students will be able to explain the terms like system, surroundings, and boundary; explain three types of system open, close and isolated systems; explain work, heat, and internal energy, etc. In this chapter, we will also discuss the first law of thermodynamics and second laws of thermodynamics and express them mathematically, internal energy, enthalpy, entropy, Gibbs energy.

## Important points of NCERT Class 11 Chemistry Chapter 6 Thermodynamics-

1. System and Surroundings - in thermodynamics, the system is the part of the universe where observations are made and the remaining universe constitutes surroundings. The universe = The system+ The Surroundings.

2. The First Law of Thermodynamics- according to it under any circumstances, energy cannot be created and nor be destroyed, it can be converted from one form to another form with the interaction of work, heat and internal energy. Mathematically, this is represented as:  $\Delta U=q+w$, where w is the work done on or by the system, q is the heat exchanged between the system and its surroundings and ΔU is the total change in internal energy of the system.

3. The second law of thermodynamics- it states that entropy of the entire universe(total entropy of both the system and its surroundings), as an isolated system, will always increase over time.
