FAQs on Thermodynamics Class 11 Notes CBSE Chemistry Chapter 6 (Free PDF Download)
1. What are the Different Types of Thermodynamic Processes?
Ans. The different types of thermodynamic processes explained in ch 6 Chemistry class 11 notes are – (1) Isothermal process, (2) Adiabatic process, (3) Isochoric process, and (4) Isobaric process.
Notes on thermodynamics class 11 Chemistry explains the thermodynamic process to be the alterations from one equilibrium macrostate into another. Within such a process, there can be energy transference from one system to another and. It may also involve work done on or by the system.
2. What is the First Law of Thermodynamics?
Ans. The First Law of Thermodynamics is lucidly explained in thermodynamics class 11 Chemistry notes. The first law is also termed as Law of Conservation of Energy. It states that there is no creation or destruction of energy. There can only be a transfer of energy; i.e., it changes from one form to another.
An example included in chapter 6 Chemistry class 11 notes explains that even though turning on light may seem to be a creation of energy, it is not so. It is merely a conversion of electrical energy into heat energy, and finally into light energy.
3. How is Thermodynamic Equilibrium Reached?
Ans. Class 11th Chemistry chapter 6 notes elaborates that thermodynamic equilibrium is reached with the transference of heat energy among objects. It means that for two objects to reach thermal equilibrium, the temperature of those has to be the same.
When two objects are brought into proximity, that is, in physical contact with each other, the property of both changes. Chapter thermodynamics class 11 Chemistry notes mention that when an alteration in property stops, thermodynamic equilibrium is said to have reached.
4. What are the Different Types of Thermodynamic Systems?
Ans. The three major types of thermodynamic systems include – (1) open system, (2) isolated system, and (3) closed system. Class 11 Chemistry chapter 6 notes discuss an open system as to include transference of mass as well as energy taking place beyond the boundary. An example of this is engines where fuel converts into power by the exchange of both mass and energy.
In case of isolated systems, there is no transference beyond surrounding’s boundary. Example of this is when hot water is kept in a thermos flask.
On the other hand, class 11 Chemistry chapter 6 thermodynamics notes explain a closed system as a medium in which energy may be transferred across the boundary, but mass will not be transferred. Due to this reason, a closed system is also termed as a fixed mass system.
