Endothermic and Exothermic Processes
Let's kick things off with the absolute basics: how energy moves! In chemistry, we talk about the 's
Energy Diagrams
If Topic 6.1 was the 'what' of energy changes, then 6.2 is the 'how it looks'! We're going to visual
Heat Transfer and Thermal Equilibrium
Alright, let's talk about heat itself! What is it? And how does it move? Here's a crucial distinctio
Heat Capacity and Calorimetry
Now we get quantitative! How much energy does it take to raise the temperature of something? That's
Energy of Phase Changes
Hold up! Why does ice water stay at 0°C even when you add heat? Because of PHASE CHANGES! This is su
Introduction to Enthalpy of Reaction
Alright, let's bring it all back to chemical reactions! The ENTHALPY OF REACTION (ΔHrxn) is the tota
Bond Enthalpies
How much energy does it take to break a bond? And how much is released when a bond forms? This topic
Enthalpy of Formation
Here's another super powerful, and often more accurate, way to calculate ΔHrxn! We're talking about
