A128 ml bubble of hot gases at 213 ∘c and 1.77 atm is emitted from an active volcano. what is the final temperature, in degrees celsius, of the gas in the bubble outside the volcano if the final volume of the bubble is 133 ml and the pressure is 0.780 atm , if the amount of gas does not change?

explanation: it gains negative electrons, therefore becoming negatively charged. as charge cannot be created, nor destroyed, only transferred, this leaves the wool positive. now that they have opposite charges, the two items attract.

it should have an internal chamber and two thermometers sticking out of the top. the internal chamber will also be closed off from the outside.

considering the question as per the attachment

here we can see that the radon nuclide has 222 as the atomic mass number and 86 as the atomic number.

when it undergoes nuclear fission it gives polonium which has atomic mass number as 218 and atomic number will be 84 along with a helium nucleus which has 4 atomic mass number and 2 as its atomic number.

222 = 218 + 4 (atomic mass number)

86 = ? + 2; therefore ? = 86-2 = 84.

the atomic mass number of polonium will be 84.
