water

chapter 3

QuestionAnswer
success of life on earth owes much to water
water makes up 70% of the planet
water has a polar covalent bond between 1 O and 2 H
electronegativity difference oxygen (-) and hydrogens (+)
water can dissociate
acids adds H+ to a solution
base removes H+ from a solution
individual hydrogen bonds are weak
hydrogen bonds hold adjacent base pairs together in double helix of DNA stable attachment and weak enough to break with little energy wasted
water's emergent property cohesion/adhesion, temperature moderation, insulation, solvent
cohesion results because of the high percentage of water molecules that bind to their neighbor
surface tension reflects the strength of cohesion; surface bonds are stronger
temperature moderation water absorbs heat from warm objects, water releases heat to cold objects
temperature measures the intensity of heat
hot= rapidly moving molecules
cold= slowly moving molecules
evaporation water molecules will transform from liquid to gas
evaporative cooling the air around an object is cooled as evaporating water absorbs heat
specific heat the amount of energy required to increase the temperature of a substance
water possesses a high specific heat temperature fluctuations of water are relatively less than other objects
insulation ice is less dense than liquid water; can insulate objects from colder temperatures
solvent any liquid that dissolves a solid, liquid, or gas
water is a powerful solvent because its polarity

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
