Day 3: Pressure Stuff

Beginning of class we used a manometer to get an understanding pressure. Picture below.

Asled about heated can and what would happen to the can when steam would leave it.

 Asked about what would happen to marshmallow if the ball jar would change pressure on them, would they grow or shrink?

The change of height of water inside the manometer would relate to atmospheric pressure. Picture below.

Pressure is F/A and density = m/V. Picture below.

Next we did some experiments to determine the ideal gas law. Picture below.

We tried different setups with a syringe and pressure sensor connected to logger pro. We did event logging. Picture below.

We graphed P vs V Picture below.

We graphed P vs T Picture below.

We graphed V vs T Picture below.

We "found" the relationship PV = nRT with our experiments. Picture below.

We then did some example problems to help our understanding of PV = nRT. Picture below.

Summary:
Found how Pressure and delta height relate to one another.
Found out the relationships between each graphs for the ideal gas law.
Worked out some problems to solidify manipulating pv = nrt. Important notes is to find out if their are any constants in the problem, and change C and gauge pressure into the right SI units.
Did diving bell problem. P = Patm + density*g*y; y being depth.(Update pictures)
