- Water
- Functions
- Reactant
- Involved in many chemical reactions including hydrolysis reactions.
- Solvent
- Some substances can dissolve in it.
- Transports substances
- Helps with temperature control
- Habitat
- Reactant
- Simple structure
- A molecules is made up of two atoms of hydrogen and one atom of oxygen. Water is a polar molecule.
- High specific heat capacity
- High latent heat of evaporation
- It takes a lot of energy to break the hydrogen bonds between water molecules,
- Very cohesive
- Cohesion is the attraction between molecules of the same type.
- This helps water flow make it great for transporting substances.
- Cohesion is the attraction between molecules of the same type.
- Good solvent
- Many substances are (ionic) are made from one positively- charged atom and one negatively- charged atom, and will attract opposite ions, Meaning they will get totally surrounded by ions.
- Water's polarity makes it a good solvent. In humans, important ions can dissolve in the water in blood.
- Many substances are (ionic) are made from one positively- charged atom and one negatively- charged atom, and will attract opposite ions, Meaning they will get totally surrounded by ions.
- Less dense when solid
- At low temperatures water freezes, water molecules are held apart in ice because each water molecule forms four hydrogen bonds making a lattice shape.
- Good for living organisms because it produces an insulating layer.
