An aluminum block with a temperature of 300oc is placed into 200 milliliters of water with a temperature of 20oc. which statement best describes what will be observed in this experiment?
group of answer choices

heat will flow from the metal to the water until both are at the temperature of the container.

heat will flow from the metal to the water until both are 300oc.

heat will flow from the metal to the water until both are 20oc.

heat will flow from the metal to the water until both are at a temperature somewhere between 20oc and 300oc.

explanation:

im pretty sure its b

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.

the correct answer would be b. amelia, because the particals of gas move really fast (charged particals) and gas also has a lot of room (particals move independently) so the only answer that has both of those is amelia's.
