may be a hot topic for the experts who prepare question papers. so as to induce more marks in class 11 Physics, it&#8217;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 \u2013 II exam. Some key points of Thermodynamics are.<\/span><span data-ccp-props=\"{&quot;134233117&quot;:true,&quot;134233118&quot;:true,&quot;201341983&quot;:0,&quot;335559739&quot;:160,&quot;335559740&quot;:240}\"> <\/span><\/p>\n<ul>\n<li><span data-contrast=\"auto\"> Equilibrium in thermodynamics refers to the situation when macroscopic variables describing the thermodynamic state of a system don&#8217;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&#8217;t at a higher temperature due to its high speed.<\/span><\/li>\n<li><span data-contrast=\"auto\"> Heat capacity, generally, depends on the method of the system that goes through when the heat is supplied.<\/span><\/li>\n<li><span data-contrast=\"auto\"> In a state of thermodynamic equilibrium, the microscopic constituents of a system aren&#8217;t in equilibrium.<\/span><\/li>\n<li><span data-contrast=\"auto\"> 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.<\/span><\/li>\n<\/ul>\n<p><b><span data-contrast=\"auto\">Subtopics of Class 11 Physics Chapter 12 Thermodynamics<\/span><\/b><span data-ccp-props=\"{&quot;134233117&quot;:true,&quot;134233118&quot;:true,&quot;201341983&quot;:0,&quot;335559739&quot;:160,&quot;335559740&quot;:240}\"> <\/span><\/p>\n<ol>\n<li><span data-contrast=\"auto\">Introduction <\/span><span data-ccp-props=\"{&quot;134233117&quot;:true,&quot;134233118&quot;:true,&quot;201341983&quot;:0,&quot;335559739&quot;:160,&quot;335559740&quot;:240}\"> <\/span><\/li>\n<li><span data-contrast=\"auto\">Thermal equilibrium <\/span><span data-ccp-props=\"{&quot;134233117&quot;:true,&quot;134233118&quot;:true,&quot;201341983&quot;:0,&quot;335559739&quot;:160,&quot;335559740&quot;:240}\"> <\/span><\/li>\n<li><span data-contrast=\"auto\">Zeroth law of Thermodynamics <\/span><span data-ccp-props=\"{&quot;134233117&quot;:true,&quot;134233118&quot;:true,&quot;201341983&quot;:0,&quot;335559739&quot;:160,&quot;335559740&quot;:240}\"> <\/span><\/li>\n<li><span data-contrast=\"auto\">Heat, internal energy, and work <\/span><span data-ccp-props=\"{&quot;134233117&quot;:true,&quot;134233118&quot;:true,&quot;201341983&quot;:0,&quot;335559739&quot;:160,&quot;335559740&quot;:240}\"> <\/span><\/li>\n<li><span data-contrast=\"auto\">First law of thermodynamics <\/span><span data-ccp-props=\"{&quot;134233117&quot;:true,&quot;134233118&quot;:true,&quot;201341983&quot;:0,&quot;335559739&quot;:160,&quot;335559740&quot;:240}\"> <\/span><\/li>\n<li><span data-contrast=\"auto\">Specific heat capacity <\/span><span data-ccp-props=\"{&quot;134233117&quot;:true,&quot;134233118&quot;:true,&quot;201341983&quot;:0,&quot;335559739&quot;:160,&quot;335559740&quot;:240}\"> <\/span><\/li>\n<li><span data-contrast=\"auto\">Thermodynamic state variables and the equation of state <\/span><span data-ccp-props=\"{&quot;134233117&quot;:true,&quot;134233118&quot;:true,&quot;201341983&quot;:0,&quot;335559739&quot;:160,&quot;335559740&quot;:240}\"> <\/span><\/li>\n<li><span data-contrast=\"auto\">Thermodynamic processes <\/span><span data-ccp-props=\"{&quot;134233117&quot;:true,&quot;134233118&quot;:true,&quot;201341983&quot;:0,&quot;335559739&quot;:160,&quot;335559740&quot;:240}\"> <\/span><\/li>\n<li><span data-contrast=\"auto\">Heat engines <\/span><span data-ccp-props=\"{&quot;134233117&quot;:true,&quot;134233118&quot;:true,&quot;201341983&quot;:0,&quot;335559739&quot;:160,&quot;335559740&quot;:240}\"> <\/span><\/li>\n<li><span data-contrast=\"auto\">Refrigerators and heat pumps <\/span><span data-ccp-props=\"{&quot;134233117&quot;:true,&quot;134233118&quot;:true,&quot;201341983&quot;:0,&quot;335559739&quot;:160,&quot;335559740&quot;:240}\"> <\/span><\/li>\n<li><span data-contrast=\"auto\">The second law of thermodynamics <\/span><span data-ccp-props=\"{&quot;134233117&quot;:true,&quot;134233118&quot;:true,&quot;201341983&quot;:0,&quot;335559739&quot;:160,&quot;335559740&quot;:240}\"> <\/span><\/li>\n<li><span data-contrast=\"auto\">Reversible and irreversible processes <\/span><span data-ccp-props=\"{&quot;134233117&quot;:true,&quot;134233118&quot;:true,&quot;201341983&quot;:0,&quot;335559739&quot;:160,&quot;335559740&quot;:240}\"> <\/span><\/li>\n<li><span data-contrast=\"auto\">Carnot Engine<\/span><span data-ccp-props=\"{&quot;134233117&quot;:true,&quot;134233118&quot;:true,&quot;201341983&quot;:0,&quot;335559739&quot;:160,&quot;335559740&quot;:240}\"> <\/span><\/li>\n<\/ol>\n<p><b><span data-contrast=\"auto\">About Infinite Learn Solutions<\/span><\/b><span data-ccp-props=\"{&quot;134233117&quot;:true,&quot;134233118&quot;:true,&quot;201341983&quot;:0,&quot;335559739&quot;:160,&quot;335559740&quot;:240}\"> <\/span><\/p>\n<p><span data-contrast=\"auto\">Infinite Learn&#8217;s mission is to create world-class learning content for students.
