Gas Laws and First Laws

The class began by predicting how a can when heated would react if then put into a bath of ice water. 


The picture above is Professor Mason heating up the can. We were supposed to predict whether the can will implode really fast, really slow, water will fill up the can or nothing. We predicted that the can would implode and we were right.



Then we decided to predict the relationships between pressure and volume. The graphs of what we predicted are shown above.


The graph above shows how pressure and temperature are correlated by doing an experiment that dealt with heating up water in a flask that is connected to a fully compressed syringe and measuring the pressure there.


The picture above shows the experiment and how it was set up by doing an experiment that dealt with heating up water in a flask that is connected to a fully compressed syringe and measuring the pressure there.


The graph above shows how pressure and temperature are correlated which in this case is directly correlated meaning as pressure increases so does temperature.


We then used the ideal gas law in order to solve a diving bell problem. It involved finding the height of air that would be present within the diving bell at a certain height. We got it to be 0.171 m.


We then decided to construct a vacuum chamber demo involving two marshmallows. The contraption above is what was used for the demo.


Lastly, we made the marshmallows inflate by decreasing the pressure and as a result we got giant marshmallows. Some people also ate them.
