Water

Pregunta	Respuesta
Water	Water is a dipole. Is a polar molecule. One end of the molecule +ve and one end -ve.
Water as a solvent	Due to this polarity, other polar molecules dissolve in water. More molecules dissolve in water compared to any other liquid, thus it is Universal Solvent.
Hydrogen Bonds	Becuase water is dipole (-ve and +ve ends), the positive end of one water molecule is attracted towards the -ve end of another molecule causing them to stick together. this property is called cohesion.
Water as a metabolite	Water is used and amde in many chemical reactions within the cells of organisms. .Hydrolysis reactions and photosynthesis use water .Condensation reactions and respiration produce water
Water as a solid	When water freezes it becomes less dense. it has the same mass but it takes up a bigger volume because the water molecules form a crystalline structure. This is why ice floats on water.
