In which case would the kinetic energy of particles be increasing? (1 point) Metal is heated from room temperature to 200°C.

Metal is melted at 1,300°C.

Metal is cooled at 1,300°C.

Metal is at room temperature, 37°C.

neither accurate nor precise.

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 =

80cm/s.

24cm/s.

53.3cm/s.
