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 vibrate in place.
They slide past each other.
They are packed very closely together.
They cause the solid to have definite volume and definite shape.
They move quickly and spread out away from each other.
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 B is a gas, because its particles move more slowly and are farther apart.
Diagram A is a gas, because its particles move more slowly and are closer together.
Diagram B is a gas, because its particles move more quickly and are farther apart.
Diagram A is a gas, because its particles move more quickly and are closer together.

Michael’s car ran over a nail, which made a hole in one of the tires. At what point will air stop pouring out of the hole in the tire?
When all of the air has escaped from the tire
When the air pressure in the tire is less than atmospheric pressure
When the air pressure in the tire is equal to atmospheric pressure.
When the air pressure in the tire is greater than atmospheric
pressure.
