Properties of air, air pressure, properties of water molecules, suspension, surface tension, and cohesion adhesion,
Prior knowledge & experience:
Why does water collect in drops? Why can water travel up a plant stem?
Why is it that the water doesn't pour out from the jar with the wire mesh lid when you turn it upside down?
1. Surface of liquid behaves as if it has a thin membrane stretched over it. The surface tension
"membrane" is always trying to contract.
2. Cohesion causes this effect.
Water will pour out of the jar because the lid with the wire mesh has holes. Water can escape form the holes.
