Question: A capillary tube is dipped in water. The height of the water column in the tube is determined by which of the following?

Options:

Correct Answer: Surface tension and density of the liquid

Solution:

The height of the water column in a capillary tube is determined by both surface tension and the density of the liquid.

A capillary tube is dipped in water. The height of the water column in the tube is determined by which of the following?

Correct Answer: Surface tension and density of the liquid

Step 1: Understand that a capillary tube is a very thin tube.
Step 2: When the tube is dipped in water, the water tries to rise inside the tube.
Step 3: The height of the water column depends on two main factors: surface tension and density.
Step 4: Surface tension is the force that makes the water molecules stick together and rise in the tube.
Step 5: Density is the mass of the water compared to its volume, which affects how high the water can rise.
Step 6: Both surface tension and density work together to determine the final height of the water column in the tube.

Capillarity – The phenomenon where liquid rises or falls in a narrow tube due to surface tension and adhesive forces between the liquid and the tube's walls.
Surface Tension – The cohesive force at the surface of a liquid that causes it to behave as an elastic sheet, influencing the height of the liquid column in a capillary tube.
Density of Liquid – The mass per unit volume of a liquid, which affects the weight of the liquid column and thus its height in the capillary tube.
