Question

step 7 do the math how much did the volume of the samples change when you pushed in the plunger? based on your results for the volume of air, what might you conclude about the shape of air in the syringe? explain.

step 8 which patterns did you observe that would help you classify any sample of matter as a solid, liquid, or gas? compare the observations that you made for the solid, liquid, and gas samples of matter. write can or cannot to make each statement true.

gases ________ change shape and ________ change volume.
liquids ________ change shape and ________ change volume.
solids ________ change shape and ________ change volume.

Explanation:

Step1: Analyze gas properties

Gases are highly compressible and take the shape of their container. When the plunger is pushed in a syringe, the volume of air (a gas) decreases. The volume change can be calculated as the initial volume minus the final volume. As for the shape, air in the syringe takes the shape of the syringe - it has no definite shape of its own and conforms to the shape of the container.

Step2: Analyze liquid properties

Liquids have a definite volume but take the shape of the part of the container they occupy. They are relatively incompressible, so they cannot change volume easily under normal conditions and can change shape to fit the container.

Step3: Analyze solid properties

Solids have a definite shape and a definite volume. They do not change shape or volume easily under normal conditions.

Answer:

Gases can change shape and can change volume.
Liquids can change shape and cannot change volume.
Solids cannot change shape and cannot change volume.
