Answer 1

Answer:

1)

An example of diffusion is the release of a drop of ink into a beaker of water.

The collision of the ink molecules with the water molecules keeps diffusion from happening quickly.

2)

A damp-proof course (DPC) is a barrier through the structure designed to prevent moisture rising by capillary action such as through a phenomenon known as rising damp. Rising damp is the effect of water rising from the ground into property.
