The paint material is pushed up to get out of the sprayer nozzle with gas escaping from the container. Note that when you open the bottle of soda quickly, the gas rushes from everywhere in the form of foam, causing a mess. So What is the cause of this mess? This mess occurs because the soda is pumped into the soda bottle by passing the water on carbon dioxide. When you open the bottle, you are actually reducing the pressure on the gas, and the volume of the gas expands. If you remove the cap quickly, the gas pushes out of the bottle.
Therefore, you should open the cap slowly and carefully until the gas comes out quietly. We are facing another phenomenon in the cases of soda bottles, which is the effervescence of soda if the bottle exposed to shaking. So what happens in this case? In this case, when the cap begins to open, the gas tries to escape from the bottle.
But, because of being mixed with the liquid, the gas brings the fluid with it and they are pushed out together, turning into foam and causing a mess. When the plunger is pulled back, you are increasing the volume in the container and thus reducing the pressure. They are inversely proportional and one must decrease while the other increases.
The liquid draws up into the syringe because it balances the pressure, making it equal to the pressure outside of the syringe. When popping a balloon, you are attempting to reduce the amount of air trapped inside of the container, thus, you increase the pressure on the system. You squeeze the balloon, increasing the pressure, which decreases the volume. The system will become too disproportional, too stressed, and must pop to equalize the system.
The same happens when you overfill a balloon, putting too much pressure proportional to the volume the container can handle. When ascending or descending in a plane, or taking a subway or train under a deep waterway, your ears "pop," or feel uncomfortable because of a change of pressure in your head.
Our ears maintain a level of water that helps you stay balanced and adjust to altitude changes. The product of pressure and volume is exactly a constant for an ideal gas. This relationship between pressure and volume is called Boyle's Law in his honor. For example, suppose we have a theoretical gas confined in a jar with a piston at the top.
Fill the syringe with water. Use the syringe to fill another balloon with some of the water, making it the same size as the air-filled balloon. Tie its opening with a knot, and trim any remaining material after the knot. Remove the plunger from the syringe so that it is open on the large end. Procedure Place the air-filled balloon just inside the large opening at the back of the syringe.
Insert the plunger into the syringe, and try to push the balloon into the tip of the syringe. How hard is it to push the plunger in?
What happens to the air inside the syringe? Pull the plunger back again, and move the balloon into the middle of the syringe. Then close the front opening the tip of the syringe with one finger, and push the plunger into the syringe again.
What do you notice? How does the balloon look or change when you push the plunger in? Release your finger from the tip of the syringe. Place the balloon into the tip of the syringe, and push the plunger into the syringe until it touches the balloon. Then close the tip of the syringe with your finger and pull the plunger all the way back. Does the balloon shape change? If yes, how? Can you explain why? Replace the air-filled balloon inside the syringe with the water-filled balloon.
Then place the plunger into the syringe. Close the tip of the syringe with your finger, and push the plunger into the syringe as far as you can. How does the balloon change this time? Release your finger from the tip of the syringe, and push the plunger all the way into the syringe until it touches the balloon at the tip of the syringe. Then close the tip of the syringe again with your finger, and try to pull the plunger back as far as you can. What happens to the water-filled balloon?
