IB Chemistry - Energetics

IB Chemistry home > Syllabus 2025 > Energetics > Heat energy

Chemistry deals with observation of the world around us and explanation of the things that happen. When chemical and physical processes happen they often do so with a change in the temperature of the medium, or surroundings. The study of energetics, or thermodynamics, seeks to explain the underlying causes of this phenomenon and to use it to make predictions as to why processes do, or don't occur.
