States of Matter

QuestionAnswer
Which describes the molecular motion of a SOLID? The molecules vibrate without colliding or moving past each other
Gases change to liquids and liquids change to solids after what? Decreases in temperature
Temperature is the measurement of the average energy of motion of the particles in a substance, so substances that have had an increase in temperature usually have what?. Changed into a liquid or gaseous state
Use the diagram: What has most likely happened when the substance changes from state Z to state Y? The temperature increased
Use the diagram: When temperature is lowered in the system, the state of the substance can change from what? From state X to state Z
Use the diagram: Based on molecular motion, the temperature of the substance at state Y is what? Higher than the temperature at state Z
Use the diagram: Based on the arrangement of the molecules in the diagram, state X is most likely characterized as a what? Gas
Students are investigating temperature changes on substances in their gaseous state. What is most likely to happen to the gaseous substance when the students decrease the temperature? Molecular motion of the atoms will decrease, causing it to change to a liquid state
What is most likely to happen to a liquid substance when the temperature is increased? Molecular motion of the atoms will increase, causing it to change into a gaseous state
When taking the temperature of a substance, one is actually measuring the what? Motion energy of the molecules or atoms
Use the diagram for Question #11: Which diagram would you use if you wanted to show a 6th grade student how atoms and molecules are arranged in a solid? 1. 2. 3. 4. Diagram 2.
Why is a gas easier to compress than a liquid or a solid? The molecules are spread out and have a lot of space between them
Use the diagram for Question # 13: Which of the following correctly identifies the classification of the diagram above? Solid
When red food coloring is added to water that has been left out in the sun it spreads out quickly. Which statement represents a conclusion supported by this observation? Molecules in warm water move faster than molecules in cold water
If it were possible for you to see gas particles at the molecular level, at room temperature, which statement correctly describes what would be observed? Molecules moving quickly, in all directions and constantly colliding with one another
Which of the following statements correctly describes a liquid substance? The atoms are more loosely connected and can slide past one another
Which statement correctly describes a solid substance? The atoms are closely locked in position in a regular pattern and can only vibrate
Which statement correctly describes a substance that exists as a gas? The atoms are free to move independently and can collide very frequently
The particles of compound X appear to be weakly attracted to each other and are able to slide past one another freely. Compound X is most likely what? Liquid
The physical condition known as the melting point is the point at which what happens? A solid material melts & A liquid material freezes
The reorganization of molecules that occurs when a substance is heated or boiled is an example of what? A physical change

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.
