# One way to determine if a relationship is inverse or direct is to find a proportionality constant , K . from the data If this relationship is direct

answer the following 7,8,9,10 it is gas laws experiment

One way to determine if a relationship is inverse or direct is to find a proportionality
constant , K . from the data If this relationship is direct A = PV . If in is inverse * = Pol .
the relationship direct or inverse ? Calculate &amp; for the seven ordered pairs in your does table
( divide or multiply the P and V values ) . Show the answers in the third column of the table
on the previous page .
Use Excel to plot the pressure ( ) VS the volume ( ) for both data sets . Attach these two
plots to your report . Do you think the relationship between the pressure and volume of a

Make an Excel plot of pressure ( P ) VS temperature in Kelvin ( K ) . Be sure to properly label
this graph , and add a linear trendline with

8 . Based on the data and graph that you obtained for this experiment , express in words the
relationship between gas pressure and temperature
Write an equation to express the relationship between press
the symbols P. T and
ure and temperature ( K ) . Use

be the temperature in Celsius at which absolute zero is realized ? Use your graph trendlin
