For all living organisms, water is the most important substance on Earth. If there would be no water on Earth, there would be no life on our planet, since life has always been closely connected to water. Due to its structure, water has many characteristics, which make it unique. Because of its molecular structure, water is a polar molecule. The unequal distribution of charges between the poles of the water molecule defines the its behaviour …showed first 75 words of 164 total…

Due to hydrogen bonding, water has a high heat capacity, which makes it different from many substances. This means you need more energy in order to change the temperature of water, that most of the other substances. The hydrogen bonding is also responsible for the specific density and its solvent properties.
