• The Top

• The Bottom

Multiple Choice

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

• Capillary Action

• Specific Heat

• Universal Solvent

• Magic

Multiple Choice

Water is a universal solvent because it...

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

Multiple Choice

Hydrogen bond

• weak attraction between two molecules (ex: water to water) that is formed due to positive and negative charges attracting

• Strong attraction between two molecules.

• Weak attraction between two molecules that is formed due to charges repelling.

• Strong attraction due to repelling of charges.

Multiple Choice

Capillary Action

• Tendency of a liquid in a tube to decrease

• Tendency of a solid to dissolve

• Tendency of a gas to condense

• the tendency of a liquid in a tube to rise

Multiple Choice

Which of the following is the correct molecular structure for water, H₂O?

Multiple Choice

Refer to the picture of water sticking to a leaf; this is occurring because of:

• Adhesion

• Cohesion

Multiple Choice

Which characteristic of water will allow a paperclip to remain floating on water when the paperclip is gently placed on top of the water?

• adhesion
• surface tension
• solvent properties
• nonpolar

Multiple Choice

Water's ability to stick to glass is

• adhesion

• cohesion

• surface tention

• capillary action

Multiple Choice

Water striders can walk across the surface of calm water. Their feet push the surface of the water down slightly, but they do not break the surface. Why?

• The insects are light enough so they do not break the hydrogen bonds holding the water molecules together
  
• The insects actually use their wings to hover slightly above the water’s surface and they only skim it with their feet.
• The insect’s feet are non-polar, so they are repelled by the polar water molecules and are pushed away from the water’s surface.
• The insects are small enough to see the individual water molecules, so they are able to step carefully from one molecule to the next

• adhesion, cohesion

• cohesion, adhesion

• capillary action, specific heat

• specific heat, capillary action
