Chemical thermodynamics || class 12 chemistry chapter 4 lec 5 #chemicalthermodynamics

‪@a2zpractical991‬ In this video, we cover Chemical Thermodynamics for Class 12 Chemistry with a clear and exam-focused explanation of work done (W), enthalpy changes, and thermochemistry. You will understand how energy changes occur during physical transformations and chemical processes, along with proper sign conventions and formulas. This lecture is specially designed for CBSE & Maharashtra Board students, helping you prepare for board exams, numericals, and concept-based questions. 📌 Topics covered: Work done in thermodynamic processes Enthalpies of physical transformations Thermochemistry basics System, surroundings & state functions Exam-oriented explanation with examples ✔ Easy language ✔ Concept clarity ✔ Board-exam focused ✔ Numericals support 📌 Hashtags: #Class12Chemistry #ChemicalThermodynamics #Thermodynamics #WorkDone #Thermochemistry #Enthalpy #PhysicalTransformations #CBSEChemistry #MaharashtraBoard #BoardExam2026 #ChemistryNumericals #NEETChemistry #ScienceEducation In this lesson, we explain Chemical Thermodynamics for Class 12, focusing on the concept of work done (W) in different thermodynamic processes. You will learn how work is calculated in isothermal, adiabatic, isobaric, and isochoric processes, along with sign conventions and graphical interpretation (P–V diagrams). We also discuss thermodynamic transitions, explaining how a system moves from one state to another and how energy is exchanged in the form of work and heat. This topic is very important for board exams, numerical problems, and competitive exams like NEET and JEE basics. ✔ Easy language ✔ Step-by-step explanation ✔ Numericals & concepts ✔ Maharashtra / CBSE Board aligned #Class12Chemistry #a2zpracticals #ChemicalThermodynamics #Thermodynamics #WorkDone #IsothermalProcess #AdiabaticProcess #IsobaricProcess #IsochoricProcess #PVGraph #BoardExamPreparation #ChemistryConcepts #NEETChemistry #CBSEChemistry #MaharashtraBoard
