Yes, size, density, etc. will change the heating rate :)

All the other chices give evidence that supports that hypothesisthat the Moon was made of material that was flung off Earth during a time when it was rapidly spinning.
Explanation:
There is an enormous amount of similarities between the minerals in the moon rocks and the rocks on earth, except that for some minerals, like potassium, their quantities are higher on the earth than on the moon.
However, there is still supports for the evidence (by the other choices) that the moon was made from a piece of earth ejected from asteroid impact in primordial earth.Explanation:It’s believed that more than 3.5 billion years during the formation of earth and before it had cooled there were frequent asteroid impacts and one enormous collision ejected a large piece of molten earth into space but within earth’s gravity influence. This piece formed the moon. Evidence of asteroid impacts are frozen in time on the moon surface thanks to the fact that the moon has no atmosphere or tectonic plates movements that wipe off this ‘evidence’.

Answer:
3AgNO₃ (aq) + Na₃PO₄(aq) → Ag₃PO₄(s) ↓ + 3NaNO₃(aq)
Explanation:
The reaction is:
3AgNO₃ (aq) + Na₃PO₄(aq) → Ag₃PO₄(s) ↓ + 3NaNO₃(aq)
3 moles of silver nitrate and 1 mol of sodium phosphate, react in order to produce 1 mol of solid silver phosphate 3 moles of sodium nitrate
3Ag⁺(aq) + PO₄³⁻ (aq) → Ag₃PO₄(s) ↓

Explanation:
Electron affinity is defined as the change in energy (in kJ/mole) of a neutral atom (in the gaseous phase) when an electron is added to the atom to form a negative ion. In other words, the neutral atom's likelihood of gaining an electron.
The electron affinity values of the following elements is given;
Electron Affinity of Hydrogen is 72.8 kJ/mol.
Electron Affinity of Lithium is 59.6 kJ/mol
electron affinity of carbon is 153.9 kJ mol‑1
Electron Affinity of Fluorine is 328 kJ/mol
The electron affinity of neon is 0 kJ mol‑1.
When nonmetals gain electrons, the energy change is usually negative because they give off energy to form an anion (exothermic process); thus, the electron affinity will be negative.
Nonmetals have a higher electron affinity than metals, meaning they are more likely to gain electrons than atoms with a lower electron affinity.
That explains why florine seems to have the highest electron affinity value.
