Frage 5
Frage
How does capillary action occur?
Antworten
-
There is a chemical action between the stem molecules and the water molecules that allow for them to create and exchange energy.
-
Water accumulates in the stem and so the water level gets higher within the stem.
-
Water molecules stick together and to the walls of the tube as they are climbing up the stem. They will continue to climb until gravity is too much.
