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

• its less dense

• hydrogen bonds result in water cohesion (surface tension)

• water is a good solvent

• water striders are afraid of water and avoid it

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

• Water is a solvent.

• Water has a high specific heat capacity.

• Water is non-polar.

A substance with a pH of 8 is

• acidic

• basic

• neutral

You body sweats to help prevent you from overheating. How does water regulate temperature?

• it lets heat pass through it

• it absorbs a lot of heat, but only increases a little in temperature

• heat is afraid of water and avoids it
