True or false
The first water pipes in the U.S were made of Cast Iron
False
They were made of hollowed logs.
What is the difference between cohesion and adhesion?
Cohesion is when two of the same polar molecules form H-bonds with each other. Adhesion is when two different polar molecules form H-bonds with each other.
