Capillarity
B
Viscosity
C
Surface tension
D
Vapor pressure
Verified step by step guidance1
Understand that the question is asking for a term that describes the resistance of a liquid's surface to being stretched or broken.
Recall the definitions of the given terms: Capillarity refers to the ability of a liquid to flow in narrow spaces without external forces; Viscosity is a measure of a liquid's resistance to flow; Vapor pressure is the pressure exerted by a vapor in equilibrium with its liquid phase.
Recognize that Surface tension is the property of a liquid that causes its surface to behave like a stretched elastic membrane, making it difficult to stretch or break the surface.
Match the definition of Surface tension to the description in the question, confirming it is the correct term.
Conclude that the term describing the difficulty to stretch or break the surface of a liquid is Surface tension.
