Concept explainers
a.
To determine:
If the statement corresponds to a liquid that has higher viscosity.
Introduction:
Viscosity of a fluid is the property of the fluid that opposes the relative motion of the fluid. This force act between the layers of the fluid. With the increase in temperature, the viscosity of the fluid decreases.
Surface tension is the force per unit length. It is the property of the fluid by which the fluid aquir least surface area.
b.
To determine:
If the stated statement corresponds to the liquid that can form more hydrogen bonds and the attractive forces present in the liquid.
Introduction:
Viscosity of a fluid is the property of the fluid that opposes the relative motion of the fluid. This force act between the layers of the fluid. With the increase in temperature, the viscosity of the fluid decreases.
Surface tension is the force per unit length. It is the property of the fluid by which the fluid aquir least surface area.
c.
To determine:
The viscosity of the fluids in term of attractive forces.
Introduction:
Viscosity of a fluid is the property of the fluid that opposes the relative motion of the fluid. This force act between the layers of the fluid. With the increase in temperature, the viscosity of the fluid decreases.
Surface tension is the force per unit length. It is the property of the fluid by which the fluid aquir least surface area.
d.
To determine:
Explanation corresponding to a small paper clip bieing able to float on water.
