<span>In the labeled portion of the curve ,you use the heat of vaporization to calculate the heat absorbed in the 4th portion. It is indicated in the picture that it is the region where vaporization occurs, that is why you need to consider this portion to calculate.</span>
Protons, neutrons, and electrons<span> are the three main subatomic particles found in an atom.</span>
A good heat insulator absorbs all, or almost all, of the heat energy
from any heat that flows through it.
A good electrical insulator absorbs all, or almost all, of the energy
from any electric current that flows through it.
A or possibly C because the other options have nothing to do with the size of the vibration. If i was you I would answer with A
