Common water is non-flammable, non-explosive, non-radioactive and not biologically hazardous. Water does not have a low specific heat. Water does not have a low surface tension or a low evaporation rate at 70 degrees Fahrenheit.
While some flammable liquids float on water, it is commonly used to extinguish fires involving solids and powders. Unless it is contaminated, water does not emit alpha, beta or gamma radiation. Water is a large percentage of the human body, making it vital to proper health. It is not poisonous at normal consumption rates.
The polarity of water molecules causes them to stick together in drops and rivulets. This gives the substance a very high surface tension that is visible to the naked eye. This property is most visible when insects walk across the surface of ponds and standing pools of water.
At 70 degrees Fahrenheit, the evaporation rate of water is very high compared to other liquids, making water available in the atmosphere in the form of water vapor. This is a critical part of the water cycle that creates the weather on the planet. This cycle provides water vapor for storms and vegetation, and it renews vital freshwater in lakes, rivers and ponds.
