Answer is: (4) emits energy as it moves to a lower energy state.
Atom emits a characteristic set of discrete wavelengths, according to its electronic energy levels.
Emission spectrum of a chemical element is the spectrum of frequencies emitted due to an atom making a transition from a high energy state to a lower energy state.
Each transition has a specific energy difference.
Each element's emission spectrum is unique.
Heat underneath the ground making its water boil
I think that the answer is 0.49
Answer:
umm i guess if there is a liquid inside it would rise to the top and the metal would sink to the bottom
