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.
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?
Question 4
4.
Match the traits to the states of matter
Have particles that slide past one another
Both shape and volume can change
Fixed shape
Solid
Question 1
1.
Read the question in the picture.
They cause the solid to have definite volume and definite shape.
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.
