what did we measure?

rate of change in pH with/wo exercise 

100

what allows us to inhale

diffs in pressure (pressure gradient)

100

what was our baseline frequency 

3500Hz

200
why was the change faster with exercise 

more energy produces more co2

200

what eq governs breathing

PV=nRT (ideal gas law)

200

how do we measure sound

comparing intensities 

300

what is the eq for pH

-log(H+)

300

what variable is changed (in ideal gas law) in a patient with pneumonia 

V (total volume is less bc of fulid)

300

what is the total range of human hearing

20-20kHz
