Bonding, Water, Acids, Bases Review

Surface tension means

• water molecules "stick" together

• water molecules "stick" to other things

• a thin skin on the surface of water

• hydrogen bonds result in weak attractions

Water is a universal solvent which means

• It can dissolve so many common substances

• It can dissolve oil

• It can't absorb a lot of energy without showing large temperature changes

• Water molecules get smaller when they freeze

What does capillary action mean?

• Water molecules are not attracted to each other

• Water molecules can defy gravity in small spaces

• Cohesion results in a thin skin forming on the surface of water

• Water molecules do not like to stick other molecules

Why is ice strange?

• As a solid, it should sink in liquid but it floats

• As a solid, it should take longer to melt

• It has a very high density

• As a solid, it should float in liquid but it sinks
