and at a shorter distance.
As length decreases, pressure increases at a higher rate.

Observation: As pressure is increasing we notice a significant
increase in the quantity of gas
particles.
Analysis Procedure: Pressure Volume Relationship
1.
Fig.1 Graph representing the relationship between volume and
pressure at constant
temperature.
2.
Fig 2 Graph representing the relationship between inverse
volume and pressure at a
constant temperature.

8. 3. The relationship between volume and pressure is an inverse
relationship because as
pressure increases, volume decreases when the temperature is
held constant. The ideal gas
equation is PV=nRT, where pressure and volume are equated to
n, moles, r, Boltzmann
constant, and t, temperature. Boyle's law equation PV=K, where
pressure and volume are
equated to constant temperature.
4. We were asked to graph the inverse volume to state Boyle’s
law that pressure is inversely
proportional to a constant temperature P=1/V.
Analysis Procedure 2: Volume Temperature Relationship
5.
Fig 3. Graph representing the relationship between temperature
and volume with
constant pressure at 17.5 atm.
6. The relationship between volume and temperature is directly
proportional. As volume
increases, temperature increases. In the equation . for the
initial volumeV 1 T 1 = V 2 T 2 V 1 T 1
and temperature of the gas and stand for the final volume and
temperature.V 2 T 2

9. 7. The temperature is in Kelvin units at the y-axis, it represents
the temperature of the gas that
we are measuring the volume of. Y= 0.568x+33.1. The slope of
the graph is 0.568.
Analysis procedure 3: Temperature Pressure Relationship
8.
Fig 4. Graph representing the relationship between pressure and
temperature at a
constant volume
9. When the volume is held constant PV=nRT can be rearranged
to . ThisP 1 T 1 = P 2 T 2
relationship is directly proportional as the pressure goes up, the
temperature also goes up and
vice-versa. Increasing the temperature causes the gas particles
to move faster. When we hold
the volume of the gas constant , the pressure and temperature

10. will increase.
10. Temperature is heat. Heat causes molecular motion to
increase causing more speed
between the particles. So when temperature decreases, volume
and pressure would decrease
too. As temperature decreases, the pressure decreases too which
causes the molecular motion
of the gas particles in the tank to slow down. This will cause the
volume to shrink due to the
slow movement.
11. Pressure of the gas is due to molecular motion with the
walls, so if the motion stops at
absolute zero, I would expect the pressure and the volume of a
gas sample will also become
zero. The pressure is 0 atm at absolute zero and all the
molecular motion stops.
Analysis Procedure 4: Pressure Quantity Relationship
12.
Fig 5. This graph represents the relationship between quantity

11. of particles and pressure.
13. The more increase in the number of gas particles in the
container, the higher the pressure.
Adding zero particles will cause the pressure to be at zero and it
slowly increases as we add
particles to the tank. I would say yes, this should be the same
for all gases.
14. When the number of moles increases, the volume and
pressure increases as well. In the
equation v/n=k express if temperature and pressure remain
constant. Therefore, the volume of
gas has a proportional relationship with the number of moles of
gas. If the number of moles
increase, the volume of gas increases.
15. The slope of the pressure vs quantity of particles
relationship graph is 0.116. The full
equation is y=0.116x+0.385. If the temperature is constant, then
the value should be the same
to other gases as well.
