Thermodynamics Made Simple Episode 5: Enthalpy & Heat Capacity

Enthalpy made simple. Many students memorise: H = U + PV But the real question is: what does it mean? In this episode, we simplify: • What enthalpy represents • Why H includes internal energy and pressure–volume energy • Why Cv relates to heating at constant volume • Why Cp relates to heating at constant pressure • Why Cp is usually greater than Cv The key idea is this: At constant volume, the system cannot expand, so no expansion work is done. At constant pressure, the system can expand, so extra energy is needed for expansion work. That is why Cp is larger than Cv. Understand this = no more confusion. #Thermodynamics101 #EngineeringConcepts #SimpleLearning #HeatCapacity #EducationTok #Awantec #NBLMEnterprise #SiswaAI #Googleforeducation #Mohe
