What fluid property enables it to withstand tensile stresses without breaking___________________?
Show answer Hide answer
Answer: C. cohesion
Explanation
Cohesion describes the molecular attraction between identical molecules, which allows liquid columns to withstand tension. This specific intermolecular force binds liquid molecules closely together to resist external pulling forces without breaking. Without adequate cohesive forces, liquids would behave entirely like gases and fail to support tensile loads. Intermolecular forces like hydrogen bonding heavily contribute to the strong cohesive properties found in water. Liquid water can sustain substantial negative pressures in clean capillary tubes due to these powerful cohesive bonds. Surface tension phenomena also stem directly from the unbalanced cohesive forces acting on molecules at liquid surfaces.
Compressibility relates to how much a fluid changes in volume when subjected to an external uniform pressure. Surface tension is an interfacial property acting along the surface plane rather than resisting internal tensile stress. Adhesion involves the attractive force between unlike molecules rather than between identical molecules of a substance.
