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.

Explanation:

Step1: Determine volume change

To find the volume change, subtract the final volume of air in the syringe (after pushing the plunger) from the initial volume of air in the syringe before pushing the plunger. Let the initial volume be $V_1$ and the final volume be $V_2$. The volume change $\Delta V=V_1 - V_2$.

Step2: Conclude about air - shape

Air in the syringe takes the shape of the syringe. Gases like air are fluid and have no definite shape of their own. They expand to fill the available space. When in a syringe, the air fills the cylindrical space of the syringe barrel, so its shape is that of the interior of the syringe (cylindrical).

Answer:

Volume change: $\Delta V = V_1 - V_2$ (where $V_1$ is initial volume and $V_2$ is final volume). Conclusion about shape: Air in the syringe takes the shape of the interior of the syringe (cylindrical) because gases have no definite shape and fill the available space.
