Question

Changes on gas win use me syringe to directly measure changes in volume Calculate the pressure in cm H_2 O, exerted in the closed end of an apparatus similar to that depicted in Figure 1 if the atmospheric pressure is 720.0 torr and the height of the water column is 22.3 cm. According to Boyles Law, gas pressure and gas volume have an inverse relationship. How would you graph gas pressure vs. gas volume in order to get a straight line? You may not copy these graphs from the web. You must draw a sample graph for this and for question #3. According to Charles' Law, gas temperature and gas volume have a direct relationship. How would you graph gas temperature vs. gas volume in order to get a straight line?

Explanation / Answer

Q1.

Total P --> Patm + Pcolumn = PAtm in cm of H2O + 22.3 cm

1033.23 cm of H2O = 1 atm

so

total P = 1033.23 + 22.3 = 1055.53 cm H2O

Q2.

You will need

1/P vs V or P vs 1/V in order to see a straight line

Q3

for direct ratio

simply

graph

P vs. T or T vs P
