Work and Heat || 11th Class Physics || Heat and Thermodynamics

Heat and work are two different ways of transferring energy from one system to another. The the distinction between Heat and Work is important in the field of thermodynamics. Heat is the transfer of thermal energy between systems, while work is the transfer of mechanical energy between two systems. This distinction between the microscopic motion (heat) and macroscopic motion (work) is crucial to how thermodynamic processes work. Heat can be transformed into work and vice verse (see mechanical equivalent of heat), but they aren't the same thing. The first law of thermodynamics states that heat and work both contribute to the total internal energy of a system, but the second law of thermodynamics limits the amount of heat that can be turned into work. The Second Law allows work to be transformed fully into heat, but forbids heat to be totally converted into work. If heat could be transformed fully into work it would violate the laws of entropy. The maximum amount of work one can attain from heat is given by the Carnot efficiency. Heat is the energy associated with the random motion of particles, while work is the energy of ordered motion in one direction. Therefore heat is "low-quality" energy and work is "high-quality" energy, and this supports the entropy statement of the Second Law. #BaseAcademyPhysics #11thClassPhysics #NabeelAkhtar #SimpleHarmonicMotion Previous Videos: Internal Energy in Urdu Hindi 👉   • Internal Energy in Urdu Hindi || 11th Clas...   Kinetic Theory of Gases 👉   • Kinetic Theory of Gases || Heat and Thermo...
