A capillary tube is dipped into water. The height to which water rises in the tube is determined by:
Surface tension and density of the liquid
Only surface tension
Only density of the liquid
Viscosity of the liquid
The height of the liquid column in a capillary tube is determined by both surface tension and the density of the liquid, as described by the capillary rise formula.

Q: A capillary tube is dipped into water. The height to which water rises in the tube is determined by:
Solution: The height of the liquid column in a capillary tube is determined by both surface tension and the density of the liquid, as described by the capillary rise formula.
Steps: 6
Step 1: Understand that a capillary tube is a very thin tube.
Step 2: 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 height to which the water rises also depends on the density of the water.
Step 5: The balance between surface tension and the weight of the water column determines how high the water will rise.
Step 6: There is a formula that combines these factors to calculate the exact height.
