A capillary tube is dipped into water. What will happen to the water level inside the tube?
Correct Answer: Water will rise in the capillary tube.
- Step 1: Understand that a capillary tube is a very thin tube.
- Step 2: Know that when the tube is dipped into water, the water tries to climb up inside the tube.
- Step 3: This climbing happens because of a force called surface tension, which pulls the water up.
- Step 4: The water level inside the tube will rise higher than the water level outside the tube.
- Capillary Action – The phenomenon where liquid rises or falls in a narrow space due to the interplay of cohesive and adhesive forces.
- Surface Tension – The elastic tendency of a fluid surface that makes it acquire the least surface area possible, contributing to capillary action.
