If a 10 percent sugar solution is separated from 20 percent sugar solution by a selectively permeable membrane in which direction will there be net movement?
The direction will be towards the more concentrated side so the 10% solution with go towards the 20% solution in an attempt to reach equilibrium.
Why are pavers more permeable than asphalt or concrete?
If you use permeable pavers. Wich are made with wider gaps. It's all in the clean stone, and size of the stone you use from sub base, base, bedding stone, and stone to fill the bond lines.The sone alows water to flow through without clogging the sytem.

What is another 'real life' example where engineers must take expansion or contraction of materials into consideration?
One example would be the construction of bridges and overpasses. Engineers need to consider the expansion and contraction of the materials used, such as concrete and steel, due to temperature changes throughout the year. Failure to account for these changes could result in structural damage or failure of the bridge due to excessive stress on the materials.
