Explanation:

The orbital diagram of an electron with eight electron is attached.  Since the 2p orbitals are filled using the maximum space available instead of pairing the electrons, this is in accord with Hund's rule.

When filling orbitals, you should put one electron in each box.  After all of the boxes in the orbital have one electron in each, you can then put the second electron into each of the boxes.

the dependant variable is spilled water

the independent is the heat

i'm pretty sure its b i might be wrong though!
