In an experiment reported in the scientific literature, male cockroaches were made to run at different speeds on a miniature treadmill while their oxygen consumption was measured. in one hour the average cockroach running at 0.08km/hr consumed 0.8 ml of o₂ per gram of insect weight at 1 atm pressure and 24 °c. this same cockroach is caught by a child and placed in a 1-qt fruit jar with a tight lid. assuming the same level of continuous activity as in the research, will the cockroach consume more than 20% of the available o₂ in a 48-hr period? (air is 21 mol percent o₂)

the ideal gas law equation is as follows

pv = nrt

where p - pressure

v - volume

n - number of moles

r - universal gas constant

t - temperature

so if the pressure, volume and temperature are already known

we are left with n and r

since r is the universal gas constant that has a known fixed value then r too is known

so we are left with 'n'

once we know temperature volume and pressure

we can find the number of moles of gas present using the ideal gas law equation

this is not my own answer, this is an answer for the same question by the user blahblahmali. i do not claim ownership of this account.

a) the particles of the chair are strongly held together.

the answer is minerals.

i believe the answer is true.
