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 and is described as the “universal solvent”and the “solvent of life”. It is the most abundant substance on the surface of Earth and the only common substance to exist as a solid, liquid, and gas on Earth’s surface. It is also the third most abundant molecule in the universe (behind molecular hydrogen and carbon monoxide).
The Base class initialize arguments for different methods such as the Electrical Resistivity Profiling and for Vertical Electrical Sounding. The Water should set the attributes and check whether attributes are suitable for what the specific class expects to.

solid,ice,gaseous,water vapororsteam. The default isNone.taste
water from ordinary sources, including bottled mineral water, usually has many dissolved substances, that may give it varying tastes and odors. Humans and other animals have developed senses that enable them to evaluate the potability of water in order to avoid water that is too
saltyorputrid. The default ispotable.odor
Pure water is usually described as tasteless and odorless, although humans have specific sensors that can feel the presence of water in their mouths,and frogs are known to be able to smell it. The default is
pure.color
The color can be easily observed in a glass of tap-water placed against a pure white background, in daylight. The default is
pure white background.appearance
Pure water is visibly blue due to absorption of light in the region ca. 600 nm – 800 nm. The default is
visible.density
Water differs from most liquids in that it becomes less dense as it freezes. In 1 atm pressure, it reaches its maximum density of
1.000 kg/m3(62.43 lb/cu ft) at 3.98 °C (39.16 °F). The default units and values arekg/m3``and ``1.magnetism
Water is a diamagnetic material. Though interaction is weak, with superconducting magnets it can attain a notable interaction. the default value is \(-0.91 \chi m\)”. Note that the magnetism succeptibily has no unit.
capacity
stands for heat capacity. In thermodynamics, the specific heat capacity (symbol cp) of a substance is the heat capacity of a sample of the substance divided by the mass of the sample. Water has a very high specific heat capacity of 4184 J/(kg·K) at 20 °C (4182 J/(kg·K) at 25 °C).The default is is ``4182 ``
vaporization
stands for heat of vaporization. Indeed, the enthalpy of vaporization (symbol \(\delta H_{vap}\)), also known as the (latent) heat of vaporization or heat of evaporation, is the amount of energy (enthalpy) that must be added to a liquid substance to transform a quantity of that substance into a gas. Water has a high heat of vaporization i.e. 40.65 kJ/mol or 2257 kJ/kg at the normal boiling point), both of which are a result of the extensive hydrogen bonding between its molecules. The default is
2257 kJ/kg.fusion
stands for enthalpy of fusion more commonly known as latent heat of water is 333.55 kJ/kg at 0 °C. The default is
33.55.miscibility
Water is miscible with many liquids, including ethanol in all proportions. Water and most oils are immiscible usually forming layers according to increasing density from the top. default is
True.condensation
As a gas, water vapor is completely miscible with air so the vapor’s partial pressure is 2% of atmospheric pressure and the air is cooled from 25 °C, starting at about 22 °C, water will start to condense, defining the dew point, and creating fog or dew. The default is the degree of condensation set to
22°C.pressure
stands for vapour pressure of water. It is the pressure exerted by molecules of water vapor in gaseous form i.e. whether pure or in a mixture with other gases such as air. The vapor pressure is given as a list from the temperature T, 0°C (0.6113kPa) to 100°C(101.3200kPa). default is
(0.611, ..., 101.32).compressibility
The compressibility of water is a function of pressure and temperature. At 0 °C, at the limit of zero pressure, the compressibility is
5.1x10^−10 P^{a^−1}. The default value is the value at 0 °C.triple
stands for triple point. The temperature and pressure at which ordinary solid, liquid, and gaseous water coexist in equilibrium is a triple point of water. The triple point are set to (.001°C,611.657 Pa) and (100 , 101.325kPa) for feezing (0°C) and boiling point (100°C) points. In addition, the triple point can be set as
(20. , 101.325 kPa)for 20°C. By default, the triple point solid/liquid/vapour is set to(.001, 611.657 Pa ).melting
stands for melting point. Water can remain in a fluid state down to its homogeneous nucleation point of about 231 K (−42 °C; −44 °F). The melting point of ordinary hexagonal ice falls slightly under moderately high pressures, by 0.0073 °C (0.0131 °F)/atm[h] or about
0.5 °C(0.90 °F)/70 atm considered as the default value.conductivity
In pure water, sensitive equipment can detect a very slight electrical conductivity of 0.05501 ± 0.0001 μS/cm at 25.00 °C. default is
.05501.polarity
An important feature of water is its polar nature. The structure has a bent molecular geometry for the two hydrogens from the oxygen vertex. The default is
bent molecular geometryorangular or V-shaped. Other possibility iscovalent bonds `` ``VSEPR theoryfor Valence Shell Electron Repulsion.cohesion
stands for the collective action of hydrogen bonds between water molecules. The default is
coherentfor the water molecules staying close to each other. In addition, the cohesion refers to the tendency of similar or identical particles/surfaces to cling to one another.adhesion
stands for the tendency of dissimilar particles or surfaces to cling to one another. It can be
chemical adhesion,dispersive adhesion,diffusive adhesionanddisambiguation. The default isdisambiguation.tension
stands for the tendency of liquid surfaces at rest to shrink into the minimum surface area possible. Water has an unusually high surface tension of 71.99 mN/m at 25 °C[63] which is caused by the strength of the hydrogen bonding between water molecules. This allows insects to walk on water. The default value is to
71.99 mN/m at 25 °C.action
stands for Capillary action. Water has strong cohesive and adhesive forces, it exhibits capillary action. Strong cohesion from hydrogen bonding and adhesion allows trees to transport water more than 100 m upward. So the default value is set to ``100.``meters.
issolvent
Water is an excellent solvent due to its high dielectric constant. Substances that mix well and dissolve in water are known as hydrophilic (“water-loving”) substances, while those that do not mix well with water are known as hydrophobic (“water-fearing”) substances.

stands for quantum tunneling. It is a quantum mechanical phenomenon whereby a wavefunction can propagate through a potential barrier. It can be
monomersfor the motions which destroy and regenerate the weak hydrogen bond by internal rotations, orhexamerinvolving the concerted breaking of two hydrogen bond. The default ishexamerdiscovered on 18 March 2016.reaction

97.39%of the global water volume of 1.38×109 km3 is found in the oceans considered as the default value.pH
stands for Potential of Hydrogens. It also shows the acidity in nature of water. For instance the “rain” is generally mildly acidic, with a pH between 5.2 and 5.8 if not having any acid stronger than carbon dioxide. At neutral pH, the concentration of the hydroxide ion (\(OH^{-}\)) equals that of the (solvated) hydrogen ion(\(H^{+}\)), with a value close to
