CBSE Class 11 Physics Chapter 12 - Thermodynamics Class 11 Notes

Thermodynamics Class 11 CBSE Revision Notes

Thermodynamics Class 11 Notes – Chapter firstly explains the zeroth law of thermodynamics. Furthermore, this law leads to the concept of temperature. Moreover, the internal energy of a system is the sum of kinetic energies and potential energies of the molecular constituents. Also, it does not include the overall kinetic energy of the system. In addition, work and heat are two modes of energy transfer of a system. Due to the temperature difference between the system and surroundings heat energy transfer arises. Besides, work-energy transfer brought other means such as moving a cylinder’s piston which contains gas.

Most noteworthy, the chapter explains the first and second laws of thermodynamics. Furthermore, the first law of thermodynamics is the general law of conservation of energy. Also, it transfers energy from or to the surroundings. In addition, the specific heat has the capacity of a substance. Besides, a calorie is the old unit of heat. Moreover, for an ideal gas, the molar specific heat capacities at constant volume and pressure satisfy the relation. Apart from that, state variables describe the equilibrium state of a thermodynamic system. Also, the reversible and irreversible process is also explained in the chapter.
