When water is boiled, the heat energy is transferred to the molecules of water, which begin to move more quickly. Eventually, the molecules have too much energy to stay connected as a liquid. When this occurs, they form gaseous molecules of water vapor, which float to the surface as bubbles and travel into the air.
Answer:
Final Temperature = 140.09K
q = 0 (Adiabatic process)
w = 7272.95J
DeltaH = -9.37KJ
DeltaU = -7272.95J

The detailed mathematical derivation from the first principle, and the appropriate substitution is as shown in the attached file.
Answer:
<span>D) combine light nuclei
</span>
Explanation:
Fission and fusion both deal with the alteration of atoms in order to produce energy. However, they are actually opposite processes, this is because:
1- Fission occurs when an atomic nucleus is split/divided into two forming two atoms
2- Fusion occurs when two light atomic nuclei combine together to form a single atom.
Hope this helps :)
