Answer:
Explanation:
If an electron is in an excited state it can return to a lower energy level. When it does this, it loses energy. The amount of energy it loses will be equal to the difference in the energy levels it moves between. This energy is released as a photon.
Heat = "A source" of energy due to a "temperature" difference.
Answer:
TUNGSTEN
Explanation:
The chemical element with the lowest boiling point is Helium and the element with the highest boiling point is Tungsten. The unity used for the melting point is Celsius (C).The stronger the IMFs, the lower the vapor pressure of the substance and the higher the boiling point.
