Introduction

Using just a syringe, and air, water and sand as representations of the 3 states of matter, we compare the compressibility of each state.

Video Overview

    • Don't poke yourself with syringe .

  1. Remove the plunger from the syringe
    • Remove the plunger from the syringe

    • Take a small piece of foam , a paper pin and synthetic glue.

    • Seal the tip of the syringe by inserting a small piece of foam through the hole using the paper pin .

    • After inserting the foam piece apply glue at the tip of the syringe . Wait for about 10 minutes for the glue to dry.

    • The tip is sealed.

    • First, we'll conduct the experiment with only air in the syringe. So simply insert the plunger.

    • Then, we'll fill the syringe with water and insert the plunger.

    • Finally, we shall do the same with the syringe filled with sand.

    • Press the plunger as far as you can when the syringe is filled with air. Note the position to which you have been able to compress.

    • Repeat the same process with the syringe filled with water.

    • And finally with sand.

    • Can you feel, show and tell which of the three is most compressible and which the least?

    • Make sure that the foam is glued firmly to the tip of the syringe such that it is airtight.

    • Fill the syringe with cotton and try to compress. Record the reading of the syringe here.

    • Remove the foam seal at the tip of the syringe in each of the 3 cases and compress. Record the syringe reading here.
