10.2 Exercise 4
You may have heard someone use the figure of speech “slower than molasses in winter” to describe a process that occurs slowly. Explain why this is an apt idiom, using concepts of molecular size and shape, molecular interactions, and the effect of changing temperature.
10.2 Exercise 6
The surface tension and viscosity of water at several different temperatures are given in this table.
(a) As temperature increases, what happens to the surface tension of water? Explain why this occurs, in terms of molecular interactions and the effect of changing temperature.
(b) As temperature increases, what happens to the viscosity of water? Explain why this occurs, in terms of molecular int…
10.2 Exercise 8
Water rises in a glass capillary tube to a height of 17 cm. What is the diameter of the capillary tube?
