Q: What is the phenomenon called when a liquid rises in a narrow tube against gravity?
Solution: Capillarity is the phenomenon where a liquid rises in a narrow tube against gravity due to adhesive and cohesive forces.
Steps: 5
Step 1: Understand that liquids can move in different ways.
Step 2: Learn that sometimes liquids can go up in a tube, even against gravity.
Step 3: Know that this upward movement is called capillarity.
Step 4: Realize that capillarity happens because of two forces: adhesive forces (liquid sticking to the tube) and cohesive forces (liquid molecules sticking to each other).
Step 5: Remember that capillarity is most noticeable in narrow tubes.
