The temperature of an ideal gas is directly proportional to the average kinetic energy of its molecules. if a container of an ideal gas is moving past you at 2000 m/s, is the temperature of the gas higher than if the container was at rest? explain your reasoning.

the temperature of the gas must have increased

Explanation:

As we know that

from this at room temperature the speed of air molecules is given as

now if the speed of the container was initially at

v = 2000 m/s

now we know that this speed is more than the speed of air molecules at room temperature

so here the temperature of the gas must have increased

it's a b and

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 =
