Q: What is the force that pulls particles at the exposed surface of a liquid toward other liquid particles called?   Read this paragraph and choose the correct option from the provided answers:  Two unique properties of liquids are surface tension and viscosity. Surface tension is a force that pulls particles at the exposed surface of a liquid toward other liquid particles. Surface tension explains why water forms droplets, like the water droplet that has formed on the leaky faucet pictured in the Figure below .
