HydrogenBonding Water HighSpecificHeat
The high specific heat of water makes a huge contribution to hydrogen bonding. Water is composed of two elements, hydrogen and oxygen. In water molecules, hydrogen and oxygen are connected by covalent bonds. However, due to the strong electronegativity of oxygen, hydrogen is slightly positively charged and oxygen is slightly negatively charged.
When many water molecules are aggregated, hydrogen bonds can be formed between the hydrogen of one water molecule and the oxygen of other water molecules. Although the force of this hydrogen bond is inferior to the covalent bond, it is numerous and has a deep impact on the properties of water.
The high specific heat of water is due to the need for energy to break the hydrogen bond between molecules when heating up. This energy not only increases the kinetic energy of molecules, but also is used to break hydrogen bonds. Therefore, it takes a lot of energy to heat up water, and the specific heat of water is higher than that of other things. When cooling, hydrogen bonds are reformed, releasing energy, causing water to cool down slowly.
In summary, hydrogen bonds exist widely among water molecules. When energy is increased, it consumes energy by breaking bonds, and when energy is reduced, it releases energy by forming bonds. This is also the main reason for the high specific heat of water.
