It explains the concept of heat of solution and provides examples of thermal reactions in hot and cold packs. The molar heat of solution is defined as the heat change per mole of solute dissolved, and sample calculations illustrate how to calculate temperature changes from the heat released when substances like sodium hydroxide dissolve in water.
