Water is an important molecule because it water is an important molecule because it has a low heat capacity is a poor solvent since few things dissolve in it can form hydrogen bonds is non-polar

 A) can form hydrogen bonds.

Water has a high heat capacity. Water is also a good solvent since many things, mostly polar chemical compound, that can be dissolved using it. Water is definitely polar. Water structure is well known to be like "Mickey mouse", causing it to have a more positive pole at the side with Mickey's ears.
Water has hydrogen bond that was causing it has a high boiling point.
