Matter

QuestionAnswer
Solid Definite Shape & Volume, Low Kinetic Energy, Molecular energy - vibrate only, Density - Tightly packed
Liquid Non - Definite Shape, Definite Volume, Medium Kinetic Energy, Molecular energy - flow over and around each other, Density - loosely spaced apart
Gas Non - Definite Shape & Volume, High Kinetic Energy, Molecular energy - move freely and quickly , Density - spaced far apart
Plasma Non - Definite Shape & Volume, Very High Kinetic Energy, Molecular energy - move freely and very quickly (highly charged), Density - spaced far apart
Physical Changes Occurs when matter takes a different form but No New Substance is created.
Chemical Changes Occurs when atoms are rearranged and one or more new substances with different chemical properties are created.
Physical Changes Examples Ice cream melting, Dissolving salt in water, Cutting your hair
Chemical Changes Examples Nail rusting, Cooking an egg, Burning wood
Pure Substances Cannot be separated by physical means. Example: Elements and Compounds.
Mixtures Can be separated by physical means. Example: Homogenous and Heterogenous
Element Contains only one type of atom. Cannot be broken down further. Na, O2
Compound Contains two or more elements chemically combined. Can only be broken down by chemical means.
Homogenous mixture Uniform throughout - looks like a single substance. Ex: Salt dissolved in water.
Heterogenous mixture Non uniform distribution - different particles can be easily distinguished. Ex: Chocolate chip cookie.
Kinetic Molecular Theory Matter is made up of atoms and molecules that are in constant motion. As temperature increases - the molecular motion increases.

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.
