What is cohesion?

• water molecules sticking to other water molecules
• water molecules sticking to different molecules
• when you dissolve a substance in a solution 
• when molecules become chemically combined

Why does ice float in water?

• Because of stronger hydrogen bonds at the surface
• The density of water as a solid is less than the density of water as a liquid
• Surface tension helps it float
• It is more dense

What is a solute?

• The substance that does the dissolving in a solution.
• The substance that is dissolved into the solution.
• The mixing of different substances.
• The process in which neutral molecules lose or gain electrons
