Answer:
B, A, A, B
Explanation:
Just trust me on this one.
Both objects have the same electrical charge. Opposite charges attract. And if they were neutral they would not do anything.
It depends on chemistry... A physical deformation to the Jell-O.
When paper burns, some of the chemical compounds in the
paper combine with oxygen in the air and become different
chemical compounds. That's a chemical change.
When iron rusts, or copper or silver turns green, that's the result
of the metal at the surface combining with the oxygen in the air and
forming a new chemical compound. Those are chemical changes.
When water evaporates, H₂O in the liquid phase gains thermal
energy and changes to H₂O in the gaseous phase. No chemical
compounds are lost, gained, or changed to other compounds.
It's just a physical change.
