- water
- oxygen molecule covalently bonded to two hydrogens
- oxygen has partial negative charge hydrogen's have partial positive
- hydrogen bonds in-between mater molecules
- oxygen has partial negative charge hydrogen's have partial positive
- polar molecule with regions of positivity and negativity
- good solvent
- its polarity makes it a good solvent, in which many different solutes can dissolve
- transport medium
- its polarity makes it a good solvent, in which many different solutes can dissolve
- high specific heat capacity
- can absorb large amounts of heat energy before its temp increases by a significant amount
- high latent heat of evaporation
- needs a lot of energy to break the hydrogen bonds in-between the water molecules to cause it to evaporate
- high c ohesion
- cohesive forces in which the water molecules attract eachother
- cappilarity
- adhesion between water and glass in a narrow tube pulls all the other water molecules up via cohesion
- Ice
- strong stable bonds between h2o molecules at 0 degrees,formed a rigid hexagonal lattice structure
- large gaps between molecules held rigidly apart means that it is less dense so floats to the top of the water
- strong stable bonds between h2o molecules at 0 degrees,formed a rigid hexagonal lattice structure
- transport medium
- oxygen molecule covalently bonded to two hydrogens
