• HO₂

• H₂O₂

• ₂H₁O

Water sticks well to many materials. What term relates to this property of water?

• cohesion

• adhesion

• density

• surface tension

What is the term for water's ability to defy gravity and climb up a tube?

• Capillary Action

• Specific Heat

• Universal Solvent

• Magic

A water strider can skate along the top of a pond because:

• covalent bonds result in water cohesion (surface tension)

• hydrogen bonds result in water cohesion (surface tension)

• water striders have adapted to take advantage of water cohesion

• water striders are afraid of water and avoid it

Why does ice float?

• water expands when it freezes, making ice less dense than water

• water compacts when it freezes, making ice more dense than water

• hydrogen bonds in water push the ice to the surface

• ice is afraid of water, and avoids it

Large bodies of water do not quickly fluctuate in temperature. Why?

• Water is a solvent.
• Water has a high heat capacity.
• Water acts as a buffer.
• Water is non-polar.

Water is a universal solvent because it...

• It can be found anywhere
• It freezes when it gets cold
• floats when frozen
• Dissolves most substances

The tightness across the surface of water that enables paper clips to float is ____________.

• adhesion
• capillary action
• surface tension
• polarity

Which property of water allows water to climb up a tree's root system to the leaves?

• Cohesion

• water's density

• Polarity

• Capillary Action
