Volume, Pressure, Temp Laws

The egg in a bottle
The egg in a bottle is an example of Gay-Lusaac's law stating; Volume is constant and temperature and pressure are directly related. This is because the volume of gas inside the flask did not change.The change of the temperature caused the change in the pressure inside the flask. when the particles inside the flask slow the pressure drops to below the amount of pressure outside the flask forcing the egg inside the flask.





Balloon in the flask
The balloon in the flask is an example of Gay-Lucsaac's law as previously stated. The flask was headed and once it has been taken off of the hot plate the water is dumped out and the balloon is placed over the mouth of the flask. The pressure inside the flask forces the balloon inside the flask when the balloon is inside the flask the balloon expands inside of the flask. The balloon expands inside the flask because the pressure on the "inside" of the balloon is greater then that inside the flask or the outside of the balloon causing the balloon to expand.





Pop Can
The pop can is an example of Gay-Lucsaac's law as previously stated. The can is on a hot plate and is heated until the water inside the can is boiling. Once the can is hot you use tongs and flip the can into the ice water. when the can is flipped into the water that traps the fast moving particles inside the can and the ice water causes the particles to stop moving immediately. This in turn causes the can to condense and crunch.
