First experiment of the day, aluminum cans are heated then placed top down in a container of ice cold water.
The basic setup for the experiment. Includes a heat source, tongs, aluminum can and a jar to hold the ice water.
First can is heated with some water inside, which turns into steam.
The can implodes from the steam turning back into water and the major volume change that results from it.
The predictions for the experiment above; we thought the can would implode, but not so fast.
Pressure and force arrows are shown in this.
Round 2, except with no water this time.
Nothing happened this time, except a little water came into the can.
The change in volume was not fast nor great enough to cause any significant changes to the can.
Listing different units for measuring pressure.
Our estimated curve for Pressure vs Volume and actual recorded values.
We collected values by hooking up a syringe to a pressure sensor and took readings upon compressing the syringe.
Our experimental values for pressure vs volume, fit with an exponential curve.
The same values except fit with an inverse graph with an offset.
The offset comes from the graph not being perfectly centered at 0 and allows the curve to fit the values better.
Professor Mason doing the same experiment with the syringe.
Now we set up a syringe hooked up to a sealed flask that will be moved into different environments of water.
The flask in room temperature water
The flask in room temperature air.
The flask in hot water.
Our predicted curve as well the actual values taken from the experiment.
The LoggerPro version of the graph.
The next experiment consists of taking the syringe and inserting the flask into water to measure the change in volume.
Due to the friction on syringe, the change in volume was not always easily seen.
Our predictions based for the relationship between temperature and volume.
Professor Mason messing around with the syringe in attempt to allow the pressure to move the plunger.
A different syringe is installed.
The syringe and flask that was in hot water and just placed into cold water.
The syringe and flask at room temperature water.
The syringe and flask in hot water.
The syringe and flask in cold water.
The syringe and flask in room temperature water again.
We solved relating Boltzmann's constant and the Ideal Gas Constant and found that R = Avogadro's number times Boltzmann's constant..
A problem involving a diving bell and submerging in water, we found how high water would rise in a diving bell given certain variables.
A deflated balloon in placed inside a vacuum, the following pictures show a sequence of what happened to the balloon.
These two are switched, can't work with blogs.
The pressure release valve is opened.
The same experiment is done, except with marshmallows.
Our predictions and results of the run.
Another sequence of photos of what occurred.
Last problem of the day, we found how much mass a given gas has when other variables are given to us.
