We started off by filling the garbage bag with air. We learned that while pushing air into the bag it would fill up and the air particles would bounce against the side of the bag making it inflate. Next we did the mercury tube experiment. What we saw in that experiment was that the air pressure actually pushed the mercury up the tube. If it's high pressure the mercury would be higher up the tube, if it's low pressure the mercury would be lower. Then we saw how the air pressure pushed the petri dish to the top of the tank because there was no air between the water and the tank so the air pushed it against the tank.
We learned the units of pressure which are: 1 atm=760 mmHg
101.3kPa=760 mmHg
1 atm=101.3 kPa
The relationship between pressure and volume was that as volume goes down pressure goes up. We saw that in the syringe because when we pushed it in volume went down and pressure went up and when we pulled it out volume went up and pressure went down.
Nice work, Brady. You summarized much of what we did during that week well. In your next blog, be sure to include some personal reflection. In other words what did you think of what we did and learned.
