Thermodynamics may be a hot topic for the experts who prepare question papers. so as to induce more marks in class 11 Physics, it’s crucial to review these solutions as one can expect many questions from this resource being asked often in entrance exams and other competitive exams. Thermodynamics is one of the foremost scoring sections in NCERT Solutions for Class 11 Physics. Students must study this Chapter in detail to score well in term – II exam. Some key points of Thermodynamics are.
- Equilibrium in thermodynamics refers to the situation when macroscopic variables describing the thermodynamic state of a system don’t depend upon time. Equilibrium of a system in mechanics refers to the net external force and torque on the system is zero. The temperature of a body is related to its average internal energy, not to the K.E. of motion of its centre of mass. A bullet fired from a gun isn’t at a higher temperature due to its high speed.
- Heat capacity, generally, depends on the method of the system that goes through when the heat is supplied.
- In a state of thermodynamic equilibrium, the microscopic constituents of a system aren’t in equilibrium.
- In isothermal quasi-static processes, heat is absorbed or given out by the system even though at every stage the gas has an equivalent temperature as that of the surrounding reservoir. this is often possible due to the infinitesimal difference in temperature between the system and the reservoir.

Q. What is the meaning of thermal equilibrium according to these NCERT Solutions?
Ans. According to NCERT Solutions of this Chapter, when an object or a body is brought in contact with another body with different temperatures, then the heat gets transferred from high temperature to low temperature until both the bodies came into thermal equilibrium. For example, when a hot cup of tea is kept at room temperature, then the heat gets transferred to the atmosphere with respect to time until the temperature of tea and atmosphere is equivalent.
