The enthalpy of hydration, also known as hydration energy, is always a negative value, meaning the process is exothermic. Understanding the **energy change of hydration** is fundamental to explaining why some salts release heat when they dissolve in water, while others absorb it.

Nearly 10% of our daily energy expenditure is used to digest and process the food we eat. So, what type of energy is digestion? It is a complex process that transforms the chemical potential energy stored within our meals into the usable energy our bodies need to function and survive.
