    Water (H 2 O) is a polar inorganic compound that is at room temperature a tasteless and odorless liquid, which is nearly colorless apart from an inherent hint of blue.It is by far the most studied chemical compound [20] and is described as the "universal solvent" [21] and the "solvent of life". [22]

    en.wikipedia.org/wiki/Outline_of_water

    Waterchemical substance with the chemical formula H 2 O. A water molecule contains one oxygen and two hydrogen atoms connected by covalent bonds. Water is a liquid at ambient conditions , but it often co-exists on Earth with its solid state, ice , and gaseous state ( water vapor or steam ).

    en.wikipedia.org/wiki/Chemical_substance

    Steam and liquid water are two different forms of the same pure chemical substance, water. A chemical substance is a unique form of matter with constant chemical composition and characteristic properties. [1] [2] Chemical substances may take the form of a single element or chemical compounds. If two or more chemical substances can be combined ...

    Dew drop on a hydrophobic leaf surface Cutting a water droplet using a superhydrophobic knife on superhydrophobic surfaces Water drops on the hydrophobic surface of grass. In chemistry, hydrophobicity is the chemical property of a molecule that is seemingly repelled from a mass of water (called a hydrophobe). [1] In contrast, hydrophiles are ...

  7. Heavy water - Wikipedia

    en.wikipedia.org/wiki/Heavy_water

    The presence of the heavier isotope gives the water different nuclear properties, and the increase in mass gives it slightly different physical and chemical properties when compared to normal water. Deuterium is a heavy hydrogen isotope. Heavy water contains deuterium atoms and is used in nuclear reactors.

    Data in the table above is given for water–steam equilibria at various temperatures over the entire temperature range at which liquid water can exist. Pressure of the equilibrium is given in the second column in kPa. The third column is the heat content of each gram of the liquid phase relative to water at 0 °C.

  9. Chemical bonding of water - Wikipedia

    en.wikipedia.org/wiki/Chemical_bonding_of_water

    In other words, if water was formed from two identical O-H bonds and two identical sp 3 lone pairs on the oxygen atom as predicted by valence bond theory, then its photoelectron spectrum (PES) would have two (degenerate) peaks and energy, one for the two O-H bonds and the other for the two sp 3 lone pairs.
