Question

water can form large dewdrops in nature. how would droplets made of vegetable oil instead of water be different?
a. oil would form droplets, but only very tiny ones because its surface tension is lower than that of water.
b. all liquids will form the same large droplets that water does.
c. oil can form the same large droplets as water because it has strong intermolecular forces.
d. oil forms slicks, not droplets, because of its molecular structure.

Explanation:

Surface tension is what allows liquids to form droplets. Water has relatively high surface - tension due to hydrogen bonding. Vegetable oil has lower surface tension than water because its intermolecular forces are weaker. Weaker surface tension means it can't hold together to form large droplets as well as water, so it would form tiny droplets.

Answer:

A. Oil would form droplets, but only very tiny ones because its surface tension is lower than that of water.
