Water is the only common substance to exist as a solid, liquid, and gas in normal terrestrial conditions. States The three common states of matter. Along with oxidane, water is one of the two official names for the chemical compound H 2 O; it is also the liquid phase of H 2 O.
5 days ago · Although its formula (H 2 O) seems simple, water exhibits very complex chemical and physical properties. For example, its melting point, 0 °C (32 °F), and boiling point, 100 °C (212 °F), are much higher than would be expected by comparison with analogous compounds, such as hydrogen sulfide and ammonia.
Jun 23, 2022 · Learn about the amazing properties and behavior of water, the most abundant substance on Earth. Discover how water exists in three states, how it dissolves things, how it makes pressure, and why it expands when it freezes.
Learn how water is the liquid that makes life on Earth possible, and how it shapes our planet and climate. Discover the amazing properties and cycles of water, and the challenges of water scarcity and pollution.
Key facts. In 2021, over 2 billion people live in water-stressed countries, which is expected to be exacerbated in some regions as result of climate change and population growth (1). In 2022, globally, at least 1.7 billion people use a drinking water source contaminated with faeces.
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 and is described as the "universal solvent" and the "solvent of life".
Sep 15, 2023 · Water regulates our internal temperature by distributing heat throughout the body and cooling it through perspiration (sweat). When the body becomes too hot, it loses water through sweat. The evaporation of sweat from the skin cools the body, keeping its temperature within a normal range.
