Matter Lesson 4: States of Matter

Sun-Yee is comparing the substances and hot water inside a ceramic cup, and the water vapor above the cup. What can she say about the motion of the particles in all of the substances?

• They do not move.
• They are always moving.
• They move past each other slowly.
• They move very fast in all directions.

How can the motion of the particles in a gas best be described?

• particles that are far apart and do not move
• particles that are close together and vibrate in place
• particles that are close together and slide past each other
• particles that are far apart and move rapidly in all directions

Nora notices water droplets on the grass in the morning. It did not rain during the night. How can the water particles in the air form water droplets on the grass during the night?

• Energy was added to the water particles, causing them to move farther apart.
• Energy was added to the water particles, causing attraction that makes them move closer together.
• Energy was taken away from the water particles, allowing them to move farther apart.
• Energy was taken away from the water particles, allowing them to move closer together.

Adnan measures the temperature of water as it changes states. He makes a graph of his data. He wants to add the properties of water that exist at each part of his graph. What labels can he add to the line between point 4 and point 5?

• definite volume, definite shape
• definite volume, changes shape
• changes volume, definite shape
• changes volume, changes shape

• a definite shape and a definite volume
• a changing shape and a definite volume
• a definite shape and a changing volume
• a changing shape and a changing volume

Demetri has a certain mass of helium. He measures how the volume of the gas changes at 10-degree temperature intervals. He creates a bar graph of his results. Why does he observe the trend shown in the graph?

• The mass of the helium increases with temperature.
• The helium particles get bigger when they are heated.
• The helium expands as vibrations between the particles that are locked in place increase.
• The amount of space between the particles increases as the helium gains more energy.
