Question 2

2.

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 are packed very closely together.

They slide past each other.

They cause the solid to have definite volume and definite shape.

Question 3

3.

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 quickly and are closer together.

Diagram B is a gas, because its particles move more slowly and are farther apart.

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 slowly and are closer together.
