Final answer:
The word 'cohere' means to hold or stick together, and it can also refer to fitting together into a logical whole. Cohesion is important in various fields such as chemistry and water properties.
Step-by-step explanation:
The word 'cohere' means to hold or stick together. It can also refer to fitting together into an orderly, logical, and unified whole. For example, in chemistry, cohesive forces bind molecules of the same type together, while adhesive forces bind a substance to a surface. In the context of water, cohesion refers to the ability of water molecules to stick together via H-bonds, which results in high surface tension.
