Lab 12: Gases
For case 1, we studied the relationship between volume and pressure and found it to be inverse relationship. To do this , we set the temperature as the constant parameter and adjusted the volume of the box so that the pressure would change.
For case 2, we studied the relationship between volume and temperature and determined that they were directly proportional. We picked a pressure and made that our constant. Then we adjusted volume and temperature and saw that they went up and down together.
For case 3, we studied the relationship between temperature and pressure and found them to be directly proportional. Volume was our constant in this one, and we adjusted the temperature to observe its relationship with pressure.
For case 4, we studied the relationship between the number of particles and volume and determined that they were directly proportional. We set pressure constant and set the number of particles to our choosing. The program changed the volume to accommodate the particles, and we saw that they increased and decreased together.
In the spreadsheet we mistyped the first point for Volume versus Pressure. In the volume column, we have the first one as 1.78cm^3, but the point does not make sense. We could not find the actual point so we only have five points for this group.

a. Bicycle tires seem more flat in the winter because of the relationship between volume and temperature. As the temperature goes down, the volume of the tire will go down too because the tire's particles slow and colliding with the boundaries of the tire less frequently.
b. A can of soda will explode if left out in the sun because of the relationship between temperature and pressure. As the temperature goes up, the pressure inside of the can will go up too due to the increasing speed of the gas particles inside. When the pressure gets so high that it can't be contained inside the can, it is released in an explosion.
c. The pressure will go down because as temperature goes down, pressure will also decreases. However, the volume should stay constant, because the container is rigid and will not expand or contract with the movement of the gas.
d. Using heat should will not help because of the relationship between heat and pressure. As heat increases, pressure will also increases. That heat would increase the pressure around the pain, and cause the person with the pain to regret his decision of not paying attention in chemistry class the day the relationships of pressure and temperature were explored.
