State of water that molecules move the slowest.

• solid

• liquid

• gas

Water is a polar molecule, which means it has a positive and a negative side. Hydrogen bonds form when:

• _{The positive end of one water molecule bonds to the positive end of another water molecule.}

• _{The negative end of one water molecule bonds to the negative end of another water molecule.}

• _{The positive end of one water molecule bonds to the negative end of another water molecule.}

The ability of water molecules to stick to each other, creating surface tension is called:

• Cohesion

• Adhesion

• Insulation

• Ph

The fact that water can stick to other substances is called:

• Ph

• Adhesion

• Cohesion

• Insulation

• When it freezes it becomes less dense

• When it freezes it becomes more dense

• When it freezes its density stays the same
