This attraction, hydrogen bonding, explains many of the properties of water, such as its solvent properties. [60] Although hydrogen bonding is a relatively weak attraction compared to the covalent bonds within the water molecule itself, it is responsible for several of the water's physical properties.
Water (data page) – Chemical data page for water is a collection of the chemical and physical properties of water. Aquaphobia – Persistent and abnormal fear of water; Blue roof – Roof of a building that is designed to provide temporary water storage; Catchwater – Runoff catching or channeling device; Human right to water and sanitation
Up to 99.63 °C (the boiling point of water at 0.1 MPa), at this pressure water exists as a liquid. Above that, it exists as water vapor. Note that the boiling point of 100.0 °C is at a pressure of 0.101325 MPa (1 atm), which is the average atmospheric pressure.
Frozen water, that is, ice. Properties of water – Physical and chemical properties of pure water Color of water – Water color in different conditions; Water vapor – Gaseous phase of water Vapour pressure of water – Pressure exerted by molecules of water vapor in gaseous form; Steam – Water in the gas phase
Physical properties of aquatic ecosystems are determined by a combination of heat, currents, waves and other seasonal distributions of environmental conditions. [13] The morphometry of a body of water depends on the type of feature (such as a lake, river, stream, wetland, estuary etc.) and the structure of the earth surrounding the body of water.
Water vapor can also be indirect evidence supporting the presence of extraterrestrial liquid water in the case of some planetary mass objects. Water vapor, which reacts to temperature changes, is referred to as a 'feedback', because it amplifies the effect of forces that initially cause the warming. Therefore, it is a greenhouse gas. [2]
Triple points mark conditions at which three different phases can coexist. For example, the water phase diagram has a triple point corresponding to the single temperature and pressure at which solid, liquid, and gaseous water can coexist in a stable equilibrium (273.16 K and a partial vapor pressure of 611.657 Pa).
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.
