Which statement best describes what is happening at the surface of liquid water?

Which statement best describes what is happening at the surface of liquid water? At the surface there is a constant exchange of liquid and gaseous water. Slow moving gas molecules are captured by the liquid water. Fast moving water molecules leave the surface and become gas molecules.

What is the most unique property of water?

Water molecules are polar, so they form hydrogen bonds. This gives water unique properties, such as a relatively high boiling point, high specific heat, cohesion, adhesion and density.

Why are liquids and solids referred to as condensed phases?

Liquids and solids are often referred to as condensed phases because the particles are very close together. The following table summarizes properties of gases, liquids, and solids and identifies the microscopic behavior responsible for each property.
