Water is polar. What does that mean?

• it is a molecule with opposite charges on opposite ends

• it is a molecule with no charge

• it is a molecule with identical charges on opposite ends

• it is a molecule with too many protons

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

• cohesion

• adhesion

• density

• surface tension

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

What are the bonds called between a slightly positive hydrogen in a polar molecule and a negatively charged atom?

• Hydrogen Bonds

• Water Bonds

• Covalent Bonds

• Bail Bonds

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
