water

Water is needed to survive.

Water is made of H2O which means there are two hydrogen bonded to oxygen

density is mass divided by volume and the density of pure water is 1.0 grams/milliliters

polarity is caused by the uneven sharing of electrons between the hydrogen and the oxygen atoms

water is a polar molecule and can only dissolve other polar substances which is why oil and water don’t mix.

hydrogen bond is formed between the water molecules because of the polarity

cohesion is the reason why water has surface tension (water bugs) and cohesion is the attraction between the water molecules themselves

adhesion is the attraction between water molecules and the surface of another substance.

it is the reason for capillary action.

water has a high heat capacity because of the hydrogen bonds which means water resists temperature change.
