• atom

• anything that has mass and takes up space

• ionic bond

• 1 atom takes electron(s) from another in a chemical bond

Which is NOT a property of water?

• cohesion and adhesion

• high specific heat capacity (changes temperature slowly)

• solid is less dense than liquid (ice floats)

• not a good solvent

Hydrogen bonding is responsible for:

• cohesion and adhesion

• you sinking in water

• evaporation

• potato

Water skaters being able to sit on top of the water is a result of

• Cohesion

• water being less dense frozen

• capillary action

• temperature

Capillary action allows water to get from the roots to the top of trees. This is a result of

• high specific heat of water

• cohesion and adhesion

• ice floating

• potatoes
