Answer 1

a is the correct answer

pls mark the answer as branliest

Answer 2

Answer is option "c"

Explanation:

• surface tension is the force behind the film formed by the surface of a liquid. These attractive forces are due to electrostatic forces. We typically refer to this cohesion at the gas-liquid surface (not liquid-solid or liquid-liquid surfaces). We often see this occur with water, but it occurs with all other liquids to some degree.
• For example, imagine a water drop sitting on a flat piece of plastic. Without surface tension, the water would spread out evenly and cover the whole surface of the plastic evenly, but instead, it sits in a single drop in the middle without flattening out. A drop of gasoline, on the other hand, will spread out very quickly across the surface. This is due to the attractive forces between the individual molecules in the water. The stronger the attraction between the particles in a liquid, the stronger the surface tension, and the less a drop like this will spread. Gasoline is bound by weak dispersion forces, but water has strong dipolar attraction and H-bonding, so gasoline will spread out but water will stay together.
• So, the  right answer is option c "surface tension"
