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

The water surface inside the capillary tube is concave due to the adhesive forces between water and the tube material being stronger than the cohesive forces among water molecules.

Using the capillary rise formula, h = (2γcosθ)/(ρgr), where γ is surface tension, θ is contact angle, ρ is density, g is acceleration due to gravity, and r is radius.

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.

The rise of water in a capillary tube is due to both surface tension (which pulls the liquid up) and adhesion (the attraction between water molecules and the tube's surface).

The water will rise in the capillary tube due to capillary action, which is a result of surface tension.

Using the formula h = 2γ/(ρgr), h = 2 × 0.072 N/m / (1000 kg/m³ × 9.81 m/s² × 0.0005 m) = 0.2 m.

For a drop to remain in equilibrium, the upward force due to surface tension must balance the downward gravitational force.

The spherical shape of a liquid drop is due to surface tension, which minimizes the surface area for a given volume.

The drop of oil spreads on water because the surface tension of water is higher than that of oil, causing the oil to spread out.

A drop of water is spherical due to surface tension, which minimizes the surface area.

The angle formed between the tangent to the drop surface and the solid surface is known as the contact angle, which indicates the wettability of the surface.

Using the formula h = 2T/(ρgr), we can calculate the height of the liquid column.

Using the formula ΔP = 2γ/r, ΔP = 2 × 0.03 N/m / 0.1 m = 0.6 Pa.

The insect can walk on water due to surface tension, which creates a 'skin' on the surface of the water.

The insect can walk on water because of surface tension, which creates a 'skin' on the surface that can support the weight of the insect.

The insect can walk on water due to surface tension, which creates a 'skin' on the surface that can support the weight of the insect.

Surface area of a sphere = 4πr² = 4π(0.1)² = 0.1256 m², approximately 0.31 m².

Surface area of a sphere = 4πr² = 4π(5)² = 100π cm².

Adding soap to water decreases the surface tension because soap molecules disrupt the cohesive forces between water molecules.

Adding soap decreases the surface tension of water.

Surfactants lower the surface tension of water by disrupting the cohesive forces between water molecules.

The addition of salt to water can increase the surface tension due to the ionic interactions that enhance the cohesive forces among water molecules.

The addition of soap decreases the surface tension of water by disrupting the cohesive forces between water molecules.

Due to surface tension, a drop of liquid will take the shape of a sphere, as this shape has the minimum surface area for a given volume.

A liquid droplet takes the shape of a sphere because this shape minimizes the surface area for a given volume, thus minimizing surface energy.

In a perfectly spherical droplet, the cohesive forces are balanced, resulting in a net force of zero.

A high surface tension indicates strong intermolecular forces, as these forces are responsible for the cohesive behavior of the liquid.

Work done = Surface Tension × Change in Area = 0.05 N/m × 1 m² = 0.05 J.

The needle floats because the surface tension of water creates a force that counteracts the weight of the needle.
