Why can’t we go to the center of the Earth?
Mandarinka [93]

Answer:

The reason why we don't fall  to the center the earth is the same reason why we don't fall to the floor when you sit down in a chair; the electrons in your body repel the electrons in the chair. More specifically, there is an electron cloud around each nucleus.

In what type of reaction or process does heat flow into the system
SCORPION-xisa [38]

Answer:  The correct answer is:  " endothermic . "

______________________________________

<u>Note</u>:  Heat flows <u> into </u>  [heat <u> may be </u> absorbed within] an "<u>endothermic</u>" reaction or system

          To the contrary, heat flows <u> </u><u>out </u>  [heat  <u> may </u><em> </em>exit from or <u> may be </u> released from] an "<u>exothermic</u>" reaction or process.

<u>Hint</u>:  Think of the "prefixes" of:  "<u>endo</u>thermic"  and "<u>exo</u>thermic" :

_____________________________________

  1)  endo- = "within" (as in "endothermic" —heat tends to be absorbed/"within"/"released within"/released within"/into" ;

  2) exo-   = " outwards"/"exit" (as in "exothermic") —heat tends to '"exit"/leave/escape from/"be released out of/form".

A gas bubble has a volume of 0.650 mL at the bottom of a lake, where the pressure is
astraxan [27]

Considering the Boyle's law, as the pressure decreases, volume increases and has a value of 2.246 mL.

<h3>Boyle's law</h3>

Boyle's law establishes the relationship between the pressure and the volume of a gas when the temperature is constant.

This law says that the volume occupied by a given mass of gas at constant temperature is inversely proportional to the pressure. This means that if the pressure increases, the volume decreases, while if the pressure decreases, the volume increases.

Boyle's law is expressed mathematically as:

P×V=k

If an initial state 1 and a final state 2 are analyzed, Boyle's law is expressed as:

P1×V1=P2×V2

<h3>Volume at the surface of the lake</h3>

In this case, you know:

  • P1= 3.46 atm
  • V1= 0.650 mL
  • P2= 1 atm
  • V2= ?

Replacing in Boyle's law:

3.46 atm× 0.650 mL= 1 atm×V2

Solving:

V2= (3.46 atm× 0.650 mL)÷ 1 atm

<u><em>V2= 2.246 mL</em></u>

Finally, as the pressure decreases, volume increases and has a value of 2.246 mL.
