Question

Rubbing alcohol evaporates from your hand quickly, leaving a cooling effect on your skin. Because evaporation is an example of a physical property, how do the molecules of gas compare to the molecules as a liquid?

Answer 1

The gas particles have a stronger attraction between them and move slower than the liquid particles.

The gas and liquid particles have the same structure and identity but different motion and kinetic energy.

The bonds inside the molecule are broken, and atoms move closer together as evaporation occurs.

The bonds are broken, and atoms spread apart as the alcohol changes phase from liquid to gas.

Answer 2

The last one.
