Which best explains the surface tension of water? -capillary action -cohesion -adhesion -sublimation

Option B, Cohesion

Explanation:

The polar nature of water causes surface tension. Water molecules being polar in nature rearrange themselves into two poles, one is positively charged while the other is negatively charged.  

The adjacent water molecules attract each other through these positive and negative poles.  

Unlike water molecules below the surface, the surface water molecules are not surrounded by other water molecules on all sides and hence they form a thin surface layer due to which an object that is submerged can move easily.  

Hence, option B is correct

answer; the tunica intima also called tunica interna, consists of elastic fibers,connective tissue and smooth muscle cells;

oxygen = 21% of the atmosphere

nitrogen = 78%

carbon dioxide = 0.1%

argon =0.934%
