Something that is viscous is thick and sticky. Another word for this might be ____________.
-
A
fluid
-
B
molten
-
C
gelatinous
-
D
malleable
Something that is viscous is gelatinous, thick, sticky, and resistant to flow due to high internal friction between molecules.
A) fluid
Fluidity denotes ease of flow, low resistance opposite to viscosity's defining characteristic. Though viscous substances are technically fluids, colloquially "fluid" implies low viscosity, creating semantic opposition.
B) molten
Molten describes phase transition to liquid state through heating, thermal property unrelated to flow resistance. Molten substances vary widely in viscosity.
C) gelatinous
Gelatinous precisely matches viscous texture: semi-solid consistency exhibiting thickness and adhesive stickiness that resists flow while maintaining cohesion. Gelatin solutions exemplify high viscosity, making gelatinous the textural descriptor capturing viscosity's resistance-to-flow essence.
D) malleable
Malleability denotes deformability under pressure without fracture, solid-state property unrelated to liquid flow resistance.
Conclusion
Viscosity denotes internal resistance to flow, distinct from fluidity, molten state, or malleability. Gelatinous alone captures viscosity's essential textural character: cohesive resistance to movement impeding pouring while maintaining substance integrity.
Topic Flashcards
Click to FlipWhat does dense mean, and how is it different from viscous?
Dense means having a high mass per unit volume (heavy for its size). Viscous refers to resistance to flow. A fluid can be dense but not viscous (like mercury), or viscous but not particularly dense (like honey).
What is the opposite of viscous, meaning a fluid that flows very easily?
Fluid (in a general sense) or, more technically, having low viscosity or being thin.
What is a high-viscosity fluid?
A fluid that flows very slowly, like honey or cold molasses. (It has high internal friction).
What does viscoelastic mean?
Having both viscous (thick, flowing) and elastic (stretchy, returning to shape) properties, like silly putty.
What is a common synonym for viscous?
Thick, sticky, gelatinous, or syrupy.
