W14 Flashcard : The Science of Slime

Front

What is shear-thinning fluid?

Back

A shear-thinning fluid is a type of non-Newtonian fluid that becomes less viscous when subjected to shear stress.

Front

What is the behavior of shear-thinning fluids under shear stress?

Back

They become less viscous under shear stress.

Front

What is the key to slime formation?

Back

The key to slime formation is cross-linking between polymer molecules and borate ions.

Front

What is shear thickening?

Back

Shear thickening is when a fluid becomes more viscous under shear stress.

Front

What is the main polymer in white glue?

Back

The main polymer in white glue is Polyvinyl Acetate (PVAc).

Front

How does borax increase the viscosity of white glue?

Back

Borax acts as a crosslinker, bonding the long chains of the polymers together.

Front

Define viscosity.

Back

Viscosity is a measure of a fluid's resistance to flow.

Front

What is a polymer?

Back

A polymer is a large molecule composed of repeating structural units (monomers) connected by covalent chemical bonds.

Front

What role do cross-linkers play in slime?

Back

Cross-linkers bond polymer chains together, increasing the viscosity and creating a gel-like structure.

Front

What is the effect of temperature on the viscosity of slime?

Back

Increasing temperature generally decreases the viscosity of slime, making it flow more easily.
