Energetics of Phase Changes | Heat of Fusion and Vaporization | Lecture 8 | Chapter 5 | Fsc 1st Year

In this lecture "Energetics of Phase Changes" from Chapter 5 – States of Matter (FSc 1st Year Chemistry), we explore the energy changes involved in phase transitions such as melting, freezing, vaporization, condensation, sublimation, and deposition. You will learn about: Enthalpy of fusion, enthalpy of vaporization, and enthalpy of sublimation How energy is absorbed or released during phase changes Heating and cooling curves explained step-by-step The role of intermolecular forces in phase transitions Why temperature remains constant during a phase change Real-life applications of phase change energetics in chemistry and daily life This lecture is prepared according to PECTAA syllabus and is perfect for FSc Pre-Medical and FSc Pre-Engineering students, competitive exam aspirants, and anyone who wants to understand thermodynamics of states of matter. 📚 Chapter: 5 – States of Matter 🎯 Lecture: 8 – Energetics of Phase Changes 🏫 Class: FSc 1st Year Chemistry 👨‍🏫 By: Zeeshan Haider – Chemistry Lover Yours Searches: Energetics of phase changes enthalpy of fusion enthalpy of vaporization enthalpy of sublimation, phase change energetics heating curve cooling curve latent heat states of matter energetics FSc 1st year chemistry lecture 8 PECTAA chemistry chapter 5 intermolecular forces and phase change thermodynamics in chemistry energy in melting boiling freezing chemistry lover lecture phase change chemistry heating and cooling curves chemistry lover zeeshan haider pectaa chemistry fsc chemistry pakistan class 11 chemistry #EnergeticsOfPhaseChanges #FScChemistry #StatesOfMatter #LatentHeat #HeatingCurve #CoolingCurve #EnthalpyOfFusion #EnthalpyOfVaporization #Thermodynamics #ChemistryLover #ZeeshanHaider #PECTAA
