Which item has the most thermal energy? A. 1 kg ice
B. 1 kg hot water just below the boiling point
C. 1 kg boiling water
D. 1 kg cold water SUBMI

if the thermos has a vacuum innner, then heat through conv currents and conduction are reduced = vacuum flask

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 =
