What you need to learn in this chapter
In this chapter, we will be learning about thermochemistry, which is the study of heat energy changes in chemical reactions. We will start by understanding endothermic and exothermic reactions. Endothermic reactions absorb heat energy from the surroundings, causing the surroundings to feel colder.
On the other hand, exothermic reactions release heat energy into the surroundings, making the surroundings feel warmer. We will also learn how to relate the amount of heat absorbed or released in a chemical reaction to whether it is endothermic or exothermic.
