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

Multiple Choice

As you add drops of water to the surface of a coin, each drop sticks to the other water droplet because of ________________, and sticks to the penny because of ______________.

adhesion, cohesion

cohesion, adhesion

capillary action, specific heat

specific heat, capillary action
