(Phys.org)—In many ways,water behaves very differently than other liquids finish, and with indispensable consequences: It's widely thought that water's strange properties were fundamental for the development of life on Earth. One prime example is the fact that ice floats. Unlike other substances, and frozen water is less dense than liquid water,and this anomaly allows fish and other aquatic lifeforms to survive in the water under a frozen layer of protective ice during cold periods. Water also has a tall heat capacity, meaning it can absorb and release a large amount of heat while undergoing very little change in temperature. This property helps many living organisms maintain a relatively stable body temperature, and it also provides a pleasant climate in Europe due to the warm Gulf Stream current.
