Introduction

There are three different states of matter namely solid, liquid and gas. Each of these states has different properties and today we will focus on understanding their compressibility property. Compressibility refers to the reduction in a particle's volume when pressure is applied to it.

In this TACtivity, we will test the compressibility property of different states of matter using a syringe.

Video Overview

    • Keep a safe distance between the candle flame and your.

    • Adult supervision is required if kids are below 8 years.

  1. Take a 5 ml syringe, a match box and a candle. Remove the plunger from the syringe. Place the syringe's tip near the candle flame to melt a small portion of the tip. Press  the melted tip of the syringe against a hard surface to completely seal the tip.

    • Remove the plunger from the syringe. Place the syringe's tip near the candle flame to melt a small portion of the tip.

    • Press the melted tip of the syringe against a hard surface to completely seal the tip.

  2. Insert a plunger into the sealed syringe containing air. Your initial reading will be the point where the plunger is located inside the sealed syringe after it was inserted (Do not push it further, yet). Note down this initial reading, as shown.

    • Your initial reading will be the point where the plunger is located inside the sealed syringe after it was inserted (Do not push it further, yet). Note down this initial reading, as shown.

    • Push the plunger slowly using your thumb until you reach a point where you cannot push it further. This point will be the final reading which you have to note down.

  3. Using a dropper,  add water into the barrel of the syringe from its open end. Place one end of the nylon thread into the syringe until it touches the water's surface. Make sure a portion of the other end of the thread remains outside the barrel. Place one end of the nylon thread into the syringe until it touches the water's surface. Make sure a portion of the other end of the thread remains outside the barrel.
    • Using a dropper, add water into the barrel of the syringe from its open end.

    • Place one end of the nylon thread into the syringe until it touches the water's surface. Make sure a portion of the other end of the thread remains outside the barrel.

  4. Pull the free end of the nylon thread, simultaneously, as you push the plunger into the barrel of the syringe. This will ensure the absence of an air gap between the plunger and the water  inside the sealed syringe. This will ensure the absence of an air gap between the plunger and the water  inside the sealed syringe. Note down the initial reading, which is the point where the plunger just touches the water's surface before compression.
    • Pull the free end of the nylon thread, simultaneously, as you push the plunger into the barrel of the syringe. This will ensure the absence of an air gap between the plunger and the water inside the sealed syringe.

    • This will ensure the absence of an air gap between the plunger and the water inside the sealed syringe.

    • Note down the initial reading, which is the point where the plunger just touches the water's surface before compression.

    • Push the plunger until you reach a point where you cannot push it further. This point will be the final reading which you have to note down.

  5. Fill sand into the syringe's barrel, from its open end. Place one end of the nylon thread halfway through the syringe's open end. Make sure a portion of the other end of the thread, remains outside the barrel. Pull the free end of the nylon thread, simultaneously, as you push the plunger into the barrel of the syringe.
    • Fill sand into the syringe's barrel, from its open end.

    • Place one end of the nylon thread halfway through the syringe's open end. Make sure a portion of the other end of the thread, remains outside the barrel.

    • Pull the free end of the nylon thread, simultaneously, as you push the plunger into the barrel of the syringe.

    • This will ensure the absence of an air gap between the plunger and the sand inside the sealed syringe.

  6. Note down the initial reading which is the point where the plunger touches the sand, after it is inserted inside the barrel. Note down the final reading which is the point where you cannot push the plunger further.
    • Note down the initial reading which is the point where the plunger touches the sand, after it is inserted inside the barrel.

    • Note down the final reading which is the point where you cannot push the plunger further.

    • The plunger goes completely inside the barrel while compressing the matter - Make sure the tip of the syringe is properly sealed.

  7. Use thermocol balls inside the syringe's barrel. Sealing the syringe using  a balloon.
    • Use thermocol balls inside the syringe's barrel.

    • Sealing the syringe using a balloon.

    • For trying the suggested variations, go to -Matter compressibility variations.
