Which statement accurately describes surface tension? A.
Attractive forces between molecules at the surface cause a liquid to resist spreading out.
B.
A liquid with larger molecules resists movement more than a liquid with smaller molecules does.
C.
A material with relatively weak bonds between its particles can be shaped into a thin sheet.
D.
A material slows or completely blocks the flow of electrons through it.

A. Attractive forces between molecules at the surface cause a liquid to resist spreading out.

Explanation:

Surface tension can be defined as a property of liquid which makes its surface to resist an external force, as a result of the cohesive nature of its molecules.

This ultimately implies that, the surface tension of a liquid is mainly caused by the cohesive forces existing between its molecules.

Hence, the statement which accurately describes surface tension is that, the attractive forces between molecules at the surface cause a liquid to resist spreading out. Also, the attractive force is due to electrostatic forces and it reduces the surface area of a liquid.

Mathematically, surface tension is given by the formula;

Surface tension = surface force)/length the force acts

γ = F /d

Where;

Γ is the Surface tension.

F is the force which applies to the liquid.

d is the length where the force acts

A
