If we compare the density and temperature of the Earth's mantle to the core, what differences can we expect as we move downward into the Earth? Both the temperature and pressure increase.

A.
Both the density and temperature increase.

B.
Both the density and temperature decrease.

C.
The density increases, and the temperature decreases.

D.
The density decreases, and the temperature increases.

the mantle

explanation:

earth is divided into three layers: the crust or the outermost layer on which we live; the underlying, middle layer - the mantle - and the core (the innermost layer of earth).

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.
