Question

Rubbing alcohol evaporates from your hand quickly, leaving a cooling sensation. Because evaporation is an example of a physical property, how do the molecules of gas compare to the molecules as a liquid? 1. The gas particles have a stronger attraction between them and move slower than the liquid. 2. The gas and liquid particles have the same structure and identity but different motion and kinetic energy. 3. The bonds inside the molecule are broken, and atoms move closer together as evaporation occurs. 4. The bonds are broken, and atoms spread apart as it changes from liquid to gas.

Answer 1

The molecules in gas are farther apart and have more room to bounce around than liquid.Gas molecules expand until they are spread out through out the space they are given while liquids take the shape of their container.
