I hope someone can help me here please don't answer nonsense​
ExtremeBDS [4]

Answer:

4560 Torr

Explanation:

<u>Boyle's Law</u>

\sf P_1 \cdot V_1=P_2 \cdot V_2

where:

  • \sf V_1 = initial volume
  • \sf V_2 = final volume
  • \sf P_1 = initial pressure
  • \sf P_2 = final pressure

Given:

  • \sf V_1 = 4 L
  • \sf V_2 = 1 L
  • \sf P_1 = 1.5 atm

Substituting the given values into the formula:

\implies \sf 1.5 \cdot 4=P_2 \cdot 1

\implies \sf P_2=6\:atm

To convert atm to Torr, multiply atm by 760:

\implies \sf P_2=6\cdot 760=4560\:Torr

Elodia [21]

Crust

Core

Explanation:

For any terrestrial planet, the crust would be the coolest layer and the core would be the hottest layer.

Terrestrial planets or the inner planets made up rocky balls. They have layers that are differentiated.

Typically, they are made up of crust, mantle and the core.

The crust is the outermost layer.

The mantle is the middle layer and core is the inner most layer.

These planets are Mercury, Venus, Earth and Mars.

The outermost layer is usually the coldest part.

The innermost layer is the hottest part which is the core
