Question

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 ...
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 / Bernoulli's 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 1

Answer:

increase

Surface tension of liquids generally ... with temperatures increases / decreases

Answer 2

Answer:

(a) As temp. decreases, surface tension increases .

(b) the viscosity of gasses is linearly proportional to the temp. hence as the temp. increase , the viscosity will increases.
