Question
O’Neill and Stachowiak studied the “extraordinary” form of this property in synovial fluid. For 10 points each:
[10h] Name this property of non-Newtonian substances that allows fluids to increase in thickness when shaken.
ANSWER: rheopecty [or rheopexy; or rheopectic fluids; accept inverse thixotropy or inverse thixotropic fluids; reject “thixotropy” or “thixotropic fluids”]
[10e] When a fluid is thixotropic or rheopectic, this quantity is time-dependent. This quantity is a fluid’s resistance to flow.
ANSWER: viscosity
[10m] Dividing the shear stress over the shear rate gives a form of viscosity named for this adjective. Unlike its counterpart, this quantity specifically refers to the resistance of movement from one fluid layer to another.
ANSWER: dynamic viscosity
