Chapters 0:00 Introduction 0:32 Two processes, two new words 1:29 Isochoric: no work at all 2:37 Isobaric: the gas pushes the piston 3:43 Topper's trick: where does the heat go? 4:46 Example 1: heating 2 mol helium at constant volume 6:06 Example 2: same heating at constant pressure, q, w, Delta U 7:56 Quick revision: isochoric vs isobaric, q : Delta U : -w A free JEE paper every day and a full JEE Main mock every Sunday: https://rankdeterminant.com/go/yt-dai...
