If you fill up a balloon with a small amount of air, then set it in direct sunlight, you will see that the balloon expands. this expansion is due to an increase in volume, which results from an increase in the temperature of the air in the balloon. this increase in temperature increases the of the gas, which results in the gas particles moving faster and colliding more often with the wall of the container. these collisions are what increase the pressure of the gas on the balloon, and ultimately cause the balloon to stretch out. a) moles b) spin energy c) kinetic energy d) potential energy

c) Kinetic energy

Explanation:

By kinetic mole theory of gas an equation is derived saying

and by ideal gas equation we know,

By combining these equations we get,

And that equation can be rearranged as,

So we find that ,

= Kinetic energy of a gas molecule.  

So as temperature increase kinetic energy of molecules increase.

Please consider that : C² = root mean square velocity

All other symbols in usual notation.

Although ideal gas equations cannot be directly applied to real gases, the behavior of real gases is similar but not as exactly according to the ideal gas equations.

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 =

its a circle not a square that's simple silly.
