Answer:
C. density
Explanation:
Density has to do with weight. Hen you pick up the Styrofoam model, you would notice how much more light it is opposed to the granite model.
Answer:
The thermal energy is the average kinetic energy of the particles in an object.
Explanation:
Hello!
In this case, since the thermal energy is associated to the temperature and the system and its effect over the molecules in the light of their movements, we infer that the proper answer is:
"The thermal energy is the average kinetic energy of the particles in an object".
On the contrary, we consider that the internal energy is referred to the total energy of the particles in the system and the translational energy is associated to the eventual movement of the system.

Answer:
The isotope with the greatest number of protons is:
- <u>option D: Pu-239, with 94 protons</u>
Explanation:
The number of <em>protons</em> is the atomic number and is a unique number for each type of element.
You can tell the number of protons searching the element in a periodic table and reading its atomic number.
Thus, this is how you tell the number of protons or each isotope
Sample Chemical symbol Element atomic number # of protons
A Pa-238 Pa protactinium 91 91
B U-240 U uranium 92 92
C Np-238 Np neptunium 93 93
D Pu-239 Pu plutonium 94 94
