(a) decreases
The
surface tension of a liquid is inversely proportional to temperature.
(b) increases;
decreases
Most
fluids offer resistance to their motion. This is like internal
mechanical friction, known as viscosity. Viscosity of gases increases
with temperature, while viscosity of liquids decreases with
temperature.
(c) Shear
strain; Rate of shear strain
With
reference to the elastic modulus of rigidity for solids, the shearing
force is proportional to the shear strain. With reference to the
elastic modulus of rigidity for fluids, the shearing force is
proportional to the rate of shear strain.
(d) Conservation
of mass/Bernoulli’s principle
For
a steady-flowing fluid, an increase in its flow speed at a
constriction follows the conservation of mass/Bernoulli’s
principle.
(e) Greater
For
the model of a plane in a wind tunnel, turbulence occurs at a greater
speed than it does for an actual plane. This follows from Bernoulli’s
principle and different Reynolds’ numbers are associated with
the motions of the two planes.
