  2. Chemical polarity - Wikipedia

    en.wikipedia.org/wiki/Chemical_polarity

    In chemistry, polarity is a separation of electric charge leading to a molecule or its chemical groups having an electric dipole moment, with a negatively charged end and a positively charged end. Polar molecules must contain one or more polar bonds due to a difference in electronegativity between the bonded atoms.

  3. Intermolecular force - Wikipedia

    en.wikipedia.org/wiki/Intermolecular_force

    The polar water molecules surround themselves around ions in water and the energy released during the process is known as hydration enthalpy. The interaction has its immense importance in justifying the stability of various ions (like Cu 2+) in water. An ion–induced dipole force consists of an ion and a non-polar molecule interacting.

  4. Properties of water - Wikipedia

    en.wikipedia.org/wiki/Properties_of_water

    Water (H2O) 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]

  5. Bent's rule - Wikipedia

    en.wikipedia.org/wiki/Bent's_rule

    Shape of water molecule showing that the real bond angle 104.5° deviates from the ideal sp 3 angle of 109.5°. In chemistry, Bent's rule describes and explains the relationship between the orbital hybridization and the electronegativities of substituents. [1][2] The rule was stated by Henry A. Bent as follows: [2] Atomic s character ...

    en.wikipedia.org/wiki/Water

    Along with the bent structure, this gives the molecule an electrical dipole moment and it is classified as a polar molecule. [94] Water is a good polar solvent, dissolving many salts and hydrophilic organic molecules such as sugars and simple alcohols such as ethanol.

  7. Water model - Wikipedia

    en.wikipedia.org/wiki/Water_model

    where μ is the electric dipole moment of the effectively polarized water molecule (2.35 D for the SPC/E model), μ 0 is the dipole moment of an isolated water molecule (1.85 D from experiment), and α i is an isotropic polarizability constant, with a value of 1.608 × 10 −40 F·m 2. Since the charges in the model are constant, this ...

  8. Thermohaline circulation - Wikipedia

    en.wikipedia.org/wiki/Thermohaline_circulation

    Thermohaline circulation. Thermohaline circulation (THC) is a part of the large-scale ocean circulation that is driven by global density gradients created by surface heat and freshwater fluxes. [1][2] The adjective thermohaline derives from thermo- referring to temperature and -haline referring to salt content, factors which together determine ...

  9. Hydrogeology - Wikipedia

    en.wikipedia.org/wiki/Hydrogeology

    Hydrogeology is an interdisciplinary subject; it can be difficult to account fully for the chemical, physical, biological, and even legal interactions between soil, water, nature, and society. The study of the interaction between groundwater movement and geology can be quite complex.
