Water Vocab

TermDefinition
Adhesion When water molecules stick to other materials.
Cohesion When water molecules stick to each other.
Polar molecule A compound with one negatively charged side and one positively charged side.
Hydrogen bond When the hydrogen(positive charge) side of a water molecule attracts the oxygen(negative charge) side of another water molecule.
Surface tension Water has high surface tension. Water has a thin skin on it's surface due to the water molecules sticking together.
Capillary action When cohesion and adhesion work together to allow water to travel against gravity and move up a plant stem.
Specific heat capacity Water has a high specific heat capacity. This is the temperature it takes to change the temperature of a substance. (Water can absorb a lot of heat before it gets hot.)
Expansion upon freezing As water gets colder, the molecules begin to move away from eachother. This means an increase in volume with the same mass leads to a decrease in density.
Universal solvent Water is called a universal solvent because it dissolves more substances than any other liquid.

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.
