Complete the following: layers: Earth as _: Sun This is an analogy by the way.
I have also attached a short paragraph about this question.

A. Milky Way galaxy
B. zero gravity
C. solid surface
D. gas

D. Gas

Explanation:

The correct option is D.

Just like the sun, there is a layer of the earth that is gas. It is known as the atmosphere.

The earth's atmosphere is known to be a layer of gases that are surrounded by the earth and retained by the earth's gravity. The gases in the earth actually contain roughly 78% nitrogen, 21% oxygen, 0.97% argon and carbon dioxide, 0.04% trace amounts of other gases, and water vapor. This combination of gases is commonly called air.

a) the particles of the chair are strongly held together.

definition

                    entropy is a measure of the randomness or the extent of disorder of a chemical process.

                      enthalpy is a measure of the heat change of a reaction occurring at a constant pressure.

measurement units:

                        entropy is measured in joule per kelvin (jk⁻¹)   whereas enthalpy is measured in joule per mole (jmol⁻¹)

requirements:

                            entropy has no requirements or limits, and its change is measured by the division between the heat change of the chemical process and the temperature.

                              in contrast, enthalpy can only be related to the heat change of the reaction under standard conditions.
