Acylinder contains oxygen at a pressure of 2.00 atm. the volume is 4.00 l, and the temperature is 300 k. assume that the oxygen may be treated as an ideal gas. the oxygen is carried through the following processes: (i) heated at constant pressure from the initial state (state 1) to state 2, which has t=450k. (ii) cooled at constant volume to 250 k (state 3). (iii) compressed at constant temperature to a volume of 4.00 l (state 4). (iv) heated at constant volume to 300 k, which takes the system back to state 1.

answer: 31, 5556. 952 seconds

it is given that trillions of microbes make up to 1% to 3% of the body mass.

let's take average of this percentage: 2%

consider the average mass of the human body as 70 kg.

then, trillions of microbes would have mass  

therefore, 100 trillion micro-organisms would weigh:

this is an approximate value and could change depending on the mass of the human body and percentage of the microbes present in it.

average mass per microorganism =
