Mercury has a very high surface tension due to strong cohesive forces between its molecules, higher than that of water, ethanol, and benzene.

Steel has a much higher Young's modulus compared to rubber, wood, and plastic, indicating it is much stiffer.

Steel is known for its elastic properties, allowing it to return to its original shape after deformation.

Steel typically has a much higher Young's modulus compared to rubber, wood, and plastic.

Steel has a much higher Young's modulus compared to rubber, wood, and plastic, indicating it is much stiffer.

Water droplets on a leaf demonstrate surface tension, as the cohesive forces between water molecules create a 'skin' on the surface.

Surface tension is responsible for capillary action, allowing liquids to rise in narrow tubes.

Viscosity describes the resistance of a fluid to flow, which is a key factor in fluid flow resistance.

Floating of heavy objects is not a consequence of surface tension; it is due to buoyancy, while the other options are directly related to surface tension.

Floating of heavy objects is not related to surface tension; it is related to buoyancy. The other phenomena are directly influenced by surface tension.

Capillary action is primarily due to surface tension, as it allows liquids to rise in narrow tubes against gravity.

The buoyant force acting on an object submerged in a fluid is equal to the weight of the fluid displaced by the object.

The elastic potential energy stored in a stretched wire is given by U = (1/2) * F * x, which is proportional to the square of the extension.

Fluids can exert pressure in all directions, which is a fundamental property of fluids.

Solids have a definite shape and volume due to the closely packed arrangement of their particles.

Surface tension generally decreases with an increase in temperature due to increased molecular motion.

Viscosity is a scalar quantity that measures a fluid's resistance to flow.

Surface tension allows the needle to float on water, as it creates a 'skin' on the surface that can support the weight of the needle.

Capillary action allows liquids to rise in narrow spaces, such as a straw, due to adhesive and cohesive forces.

Surface tension causes small droplets to minimize their surface area, resulting in a spherical shape.

Archimedes' principle states that a body submerged in a fluid experiences an upward buoyant force equal to the weight of the fluid displaced.
