Properties of Water

TermDefinition
Covalent Bonding A type of chemical bond where atoms share electrons to stay connected. For example, in a water molecule (H₂O), oxygen and hydrogen share electrons to form strong bonds
Hydrogen Bnding A weaker bond that forms between molecules when a hydrogen atom in one molecule is attracted to a very electronegative atom (like oxygen) in another molecule. For instance, this happens between water molecules, helping them stick together
Polarity a molecule has a positive charge on one side and a negative charge on the other. Water is polar because its oxygen atom pulls electrons more strongly than the hydrogen atoms,.This polarity allows water to form hydrogen bonds
Cohesion the tendency of similar molecules to stick together. In water, cohesion happens because water molecules are attracted to each other due to hydrogen bonding. This is why water forms droplets instead of spreading out completely
Adhesion when molecules of one substance stick to molecules of another substance. For example, water sticks to glass or plant walls because of its polarity, which helps it climb up surfaces like in capillary action
Surface Tension the "skin" that forms on the surface of water due to cohesion. It allows small objects, like insects or paper clips, to rest on the surface without sinking, even though they are denser than water
Specific Heat the amount of energy needed to raise the temperature of water by 1°C. Water has a high specific heat, meaning it heats up and cools down slowly. This helps regulate temperatures in nature and our bodies
Capillary Action when water moves up narrow spaces, like in plant stems or paper towels. This happens because adhesion makes water stick to the surface, while cohesion pulls more water along with it

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.
