Adhesion is the attraction between different substances. When the edges of water curve upward in a test - tube, it's because water molecules are attracted to the glass of the test - tube, which is adhesion. Cohesion is the attraction between like substances. When water forms a low dome in a full test - tube, it's due to the cohesive forces between water molecules. When table salt is dissolved in water, water acts as a solvent, dissolving the solute (table salt).
