Fill in the blanks using the word(s) from the list appended with each statement: (a) Surface tension of liquids generally . .. with temperatures (increases / decreases) (b) Viscosity of gases . .. with temperature, whereas viscosity of liquids . .. with temperature (increases / decreases) (c) For solids with elastic modulus of rigidity, the shearing force is proportional to . .. , while for fluids it is proportional to . .. (shear strain / rate of shear strain) (d) For a fluid in a steady flow, the increase in flow speed at a constriction follows (conservation of mass / Bernoullis principle) (e) For the model of a plane in a wind tunnel, turbulence occurs at a ... speed for turbulence for an actual plane (greater / smaller)
Answer:
(a) Decreases
(b) Not the gases increases ; not the liquid decreases
(c) shear strain; rate of shear strain
(d) conservation of mass; Bernoullis principle
(e) Greater
