Adhesion water molecules stick to other materials.
Cohesion the occurrence of water sticking to other water molecules via hydrogen bonds
Polar molecule A compound with one negatively charged side and one positively charged side
Hydrogen bond The side with the hydrogen atoms (positive charge) attracts the oxygen side (negative charge) of a different water molecule.
Surface tension water has a thin "skin" on its surface due to the water molecules sticking together.
Capillary action Cohesion and adhesion work together to allow water to travel against gravity and move up a plant stem
Specific heat capacity Specific heat is the amount of heat required to change the temperature of a unit mass of a given substance by a unit amount (usually a degree)
Expansion upon freezing As water decreases in temperature, the molecules move away from each other. This change causes an increase in volume
