VII.+adhesion+and+cohesion

__Cohesion__
-the **intermolecular** (like/same molecules) **force** that holds together the molecules in a solid or liquid -in water, the water droplets are held together by **cohesive forces** (water molecule is attracted to other water molecules) -"The oxygen end of water has a negative charge and the hydrogen end has a positive charge. The hydrogens of one water molecule are attracted to the oxygen from other water molecules. This attractive force is what gives water its cohesive and adhesive properties."
 * -**stronger cohesive forces in water is at the top --> surface tension

The cohesive force between the water molecules

__Adhesion__
-"the molecular force of attraction in the area of contact between unlike bodies that acts to hold them together" -adhesion is when a substance such as water is attracted to other materials such as glass -for example: there is no adhesion between petroleum jelly and water, causing it to form little water beads. However, there is adhesion between glass and water, as seen in the capillary tube experiment. The water climbs up the tube and sticks to the glass.
