Water can moderate temperature because of the two properties: high-specific heat and the high heat of vaporization. High-specific heat is the amount of energy that is absorbed or lost by one gram of a substance to change the temperature by 1 degree celsius.
This attraction, hydrogen bonding, explains many of the properties of water, such as its solvent properties. Although hydrogen bonding is a relatively weak attraction compared to the covalent bonds within the water molecule itself, it is responsible for a number of water's physical properties.

The properties of water are special because of the way its atoms bond together to form a water molecule, and the way the molecules interact with each other. Water Polarity When the two hydrogen atoms bond with the oxygen , they attach to the top of the molecule rather like Mickey Mouse ears.
Water freezes to form ice, ice thaws to form liquid water, and both water and ice can transform into the vapor state. Phase diagrams help describe how water changes states depending on the pressure and temperature. Phase diagram of water. The three phases of water – liquid, solid, and vapor – are shown in temperature-pressure space.
Water has high specific heat, high heat of vaporization, and an evaporative cooling property that together causes it to tend to maintain a constant temperature. Water temperatures can change, of course, they just change more slowly than the temperatures of other substances. Each of these properties is due to the hydrogen bonding property of water.
The nature of the atomic structure of water causes its molecules to have unique electrochemical properties. The hydrogen side of the water molecule has a slight positive charge (see Figure 8a-1). On the other side of the molecule a negative charge exists.
I would like to nominate water (H2O) to be the most unusual and cool chemical substanace as it possess many such properties that scientifically it should not have..Everyone knows water is precious and vital to life. It makes up around half of our ...
