[AI-generated answer — Bot GPT 3.5]

Cohesion refers to the ability of molecules of the same substance to be attracted and stick to each other. In the case of water, it is the ability of water molecules to be attracted to each other and form hydrogen bonds, which gives water its high surface tension. This cohesive property is also responsible for phenomena like capillary action, where water can move against gravity in narrow spaces.
