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.

"hydrogen bonding is the attraction of h atoms in the water molecule (slight + charge) to o atoms in a neighboring water molecule (slight - charge); it is a weak interatomic force. but it is still strong enough to the water molecules "stick" together."

the product of the pressure and volume is also constant

atomic mass = 39

number of neutrons = 20

number of protons= 19

electronic configuration = 1s2 2s2 2p6 3s2 3p6 4s1

the number of electron in first shell = 2

number of electrons in n=3 shell = 8
