Background Research

The Balloons In the Vacuum Chamber experiment requires certain materials and application of certain laws:

Boyle's Law:A gas law, stating that the pressure and volume of a gas have an inverse relationship, when temperature is held constant.

Vacuum Chamber:A rigid enclosure from which air and other gases are removed by a vacuum pump. This results in a low pressure environment within the chamber, commonly referred to as a vacuum.

Balloon's: Brightly colored sacs of stretchable rubber most commonly used as decorations. It is sealable by the neck and it is used to put small amounts of any air for a certain amount of time.

What will happen in the experiment is that the balloon will be put into a vacuum chamber. Now what the vacuum chamber does is it extracts all the air inside the glass chamber. When extracting the gas or any air trapped inside the glass chamber the balloon will begin to expand. This happens because of Boyle's law. Because of Boyle's law of volume balancing with pressure the balloon expands in order to be balanced with the pressure.

The formula for Boyle's law is P₁+V₁=P₂+V_{2. His law gives the relationship between pressure and volume if temperature and amount are held constant. If the volume of a container is increased, the pressure decreases. If the volume of container decreases, the pressure decreases. If the volume is increased this means that gas molecules will have farther to go and they will impact the walls of the container less frequently. This means the gas pressure will be less because there are less molecule impacts. If the volume is decreased the gas molecules have a shorter distance to go, so they will strike the walls more frequently. This results in pressure being increased because there are more molecules impacting the walls. An example would be}

(2.00 L of a gas is at 740.0 mmHg pressure. What is its volume at standard pressure? This problem is solved by inserting values into P₁V₁ = P₂V₂. (740.0 mmHg) (2.00 L) =(760.0 mmHg) (x)

The balloons are being expanded inside the vacuum chamber.

What is Boyle's Law?

Boyle's Law is when pressure goes up the volume gets smaller IF temperature and quantity are held constant.

Pressure,Quantity, and Temperature are what make Boyle's Law happen.

P is the amount of pressure being acted

V is the amount of volume present

Why is Boyle's Law Important?

Boyle's Law gives us important information about the behavior of gases. In this case, we find that pressure and volume of a gas are inversely proportional to one another, so if we push on it real hard it squishes into a smaller volume.

This turns out to be handy because it's frequently nice to pressurize gases. When we go scuba diving, we use compressed air to keep from dying, and it's good to know that the tanks aren't going to explode because the people who built them understood that the pressure inside would be high.

How did Boyle find out?

Robert Boyle employed a J-shaped piece of glass tubing that was sealed on one end. A gas (air) was trapped in the sealed end of the tube and varying amounts of mercury were added to the J-shaped tube to vary the pressure of the system. Boyle systematically varied the pressure and measured the volume of the gas. These measurements were performed using a fixed amount of gas and a constant temperature. In this way Boyle was able to examine the pressure-volume relationship without complications from other factors such as changes in temperature or amount of gas.
