Chelsea went ice-skating. The ice, her skates, the Zamboni, and the rink building itself were all examples of solids she encountered. She developed a model of the particles in the ice. Which of these statements about the particles present in her model of a solid are true?
Choose the three statements that apply.
They slide past each other.
They vibrate in place.
They are packed very closely together.
They cause the solid to have definite volume and definite shape.
Many technologies use enclosed fluids. For example, a hydraulic press at an auto repair shop uses trapped water to lift heavy cars. Hot-air balloons heat trapped air to lift a basketful of people.
Look at the two diagrams that model fluid particles.
Which statement best identifies which of these models represents a gas?
Diagram A is a gas, because its particles move more slowly and are closer together.
Diagram A is a gas, because its particles move more quickly and are closer together.
Diagram B is a gas, because its particles move more quickly and are farther apart.
Diagram B is a gas, because its particles move more slowly and are farther apart.
Match the traits to the states of matter
Both shape and volume can change
Has the LEAST energy of all of these states
Fixed volume, but NOT fixed shape
Fixed shape
Has the MOST energy of all of these states
Have particles that slide past one another
Solid
Liquid

Evidence: Which evidence from the image best supports your claim above?
The molecules are tightly packed together showing a solid state of matter.
The molecules are tightly packed together showing a liquid state of matter.
The molecules are tightly packed together showing a gas state of matter.
