Anchor Summary:
Water is a molecule, all life could not survive with water. Water has many properties but something to keep in mind is the fact that water is polar that has one electronegative oxygen that keeps the electrons closer to it than to the hydrogens its bonded to which gives oxygen a slightly negative charge. The electrons are spending more time next to it and gives the hydrogen a slightly positive charge .Other water molecules have a easy time bonding because the hydrogen of one molecule with its slightly positive charge can bond to another molecule with the bonds of oxygen with a slightly negative charge. These bonds are hydrogen bonds which allows water to have many properties.Water sticks to the xylem walla which is known as adhesion (helps fight gravity) and can also bond to each other called cohesion which helps it stick.

Vocabulary!
Lipids: a fatty organic compound that is insoluble in polar solvents but soluble in nonpolar solvents.
Cohesion: refers to the sticking together of a like molecules, such as water molecule being attracted to another water molecule. Cohesion also causes water molecules to form drops
Adhesion: refer to the joining of two different substances due to attractive forces that hold them.
Specific-heat: Specific heat is the amount of heat energy required to raise the temperature of a body per unit of mass.
Freezing point: The freezing point is the temperature at which a liquid change to a solid. The freezing point of a substance is not necessarily the same as its melting point.
