In this session, Shikha Munjal will discuss the first law of thermodynamics, second law of thermodynamics from the chapter "Thermodynamics". Heat observed by the system = its internal energy + work done by the system. Open System: In a system, when there is exchange of energy and matter taking place with ΔH and qp both are +Ve. • Intensive property Process which takes place at constant volume. • Molar heat capacity dP = 0 ΔH = qp The best app for CBSE students now provides Thermodynamics class 11 Notes Chemistry latest chapter wise notes for quick preparation of CBSE exams and school based annual examinations. (ii) If ΔG is positive (> 0) the process is non-spontaneous. Thanks for subscribing! The increase in temperature is proportional to the heat transferred. The chapters that are included in the answer booklet are: Some basic concepts of chemistry; Structure of atom; Classification of elements and periodicity Intensive properties do not depend upon the size of the matter or quantity of the matter present in the system. • Gibbs Energy and Spontaneity The total enthalpy change of a reaction is the same, regardless of whether the reaction is completed in one step or in several steps. It is surrounded by a water bath to ensure that no heat is lost to the surroundings. Thermodynamics. Its actual speed can vary from very slow to quite fast. q is +ve when heat is transferred from the surroundings to the system.
