Water (Chemical Formula: H₂O) refers to a chemical substance consisting of two hydrogen atoms attached to the central oxygen atom via a covalent bond. Apart from liquid, water may also occur in other forms such as gas (as water vapor) and solid (as ice).

What is water explain?

water, a substance composed of the chemical elements hydrogen and oxygen and existing in gaseous, liquid, and solid states. It is one of the most plentiful and essential of compounds. A tasteless and odourless liquid at room temperature, it has the important ability to dissolve many other substances.

What is water simple?

Water is a colorless and odorless substance found all over Earth. Water is made up of billions of molecules. Each molecule is made of one oxygen and two hydrogen atoms held together by strong covalent bonds. All living things need water in some form to survive on Earth.

What are the types of water in biology?

They are: (1) Gravitational Water or Ground Water (2) Capillary Water (3) Hygroscopic Water and (4) Chemically Combined Water.

Is water part of biology?

Water is one of the most unique molecules known to man and also one of the most important to biological systems. Not only does water exist in nature in all three states of matter (solid, liquid, gas), it also covers 75 percent of the earth and composes roughly 78 percent of the human body.

What is water called in science?

Water (chemical formula H₂O ) is an inorganic, transparent, tasteless, odorless, and nearly colorless chemical substance, which is the main constituent of Earth’s hydrosphere and the fluids of all known living organisms (in which it acts as a solvent).

What is water in Earth science?

Water is simply two atoms of hydrogen and one atom of oxygen bonded together. Despite its simplicity, water has remarkable properties. Without water, life might not be able to exist on Earth and it certainly would not have the tremendous complexity and diversity that we see.

What is h2o in chemistry?

The chemical symbol (see also symbol) for water. Each molecule of water contains two atoms of hydrogen (H) joined to a single atom of oxygen (O).

What is h2o full name?

H₂O is the molecular formula of water, also called Dihydrogen monoxide. H₂O symbolises two hydrogen atoms and one oxygen atom.

What is water and its type?

. The main types. of water are atmospheric (0.001 percent of total volume), the oceans (96.4 percent), fresh surface water, saline lakes, and land-locked seas (0.013 percent), groundwater (1.68 percent), and glaciers (1.86 percent). Earth’s water can exist in three phases: liquid, solid, and gaseous.

What is a type of water?

Most people don’t realize that there are three different types of water: utility grade, working grade, and drinking water. It’s helpful to be aware of these different types of water, so that we understand how they are used and to better educate us on the level of treatment recommended for each kind.

How H2O is formed?

The actual reaction to make water is a bit more complicated: 2H2 + O2 = 2H2O + Energy. In English, the equation says: To produce two molecules of water (H2O), two molecules of diatomic hydrogen (H2) must be combined with one molecule of diatomic oxygen (O2). Energy will be released in the process.

What is the water answer?

Answer: Water is a compound of hydrogen and oxygen. Water is a pure substance and not a mixture. The chemical formula for water is H₂​O, that is each molecule of water consists of one oxygen atom chemically bonded to two hydrogen atoms.

Is water a cell?

Water is the most abundant molecule in cells, accounting for 70% or more of total cell mass. The critical property of water in this respect is that it is a polar molecule, in which the hydrogen atoms have a slight positive charge and the oxygen has a slight negative charge (Figure 2.1).

What is water use?

Water can be used for direct and indirect purposes. Direct purposes include bathing, drinking, and cooking, while examples of indirect purposes are the use of water in processing wood to make paper and in producing steel for automobiles. The bulk of the world’s water use is for agriculture, industry, and electricity.
