The pressure inside a compressed gas cylinder is 144 atm at 48°C. What will the pressure inside the cylinder be after it is cool
Andrews [41]
<h3>Answer:</h3>

134 atm

<h3>Explanation:</h3>
  • Based on the pressure law, the pressure of a gas varies directly proportionally to the absolute temperature at a constant volume.
  • Therefore; we are going to use the equation;

\frac{P1}{T1}=\frac{P2}{T2}

In this case;

Initial pressure, P1 = 144 atm

Initial temperature, T1 (48°C) = 321 K

Final temperature, T2 (25°C) = 298 K

We need to find the final pressure,

Therefore;

P2 = (P1/T1)T2

    = (144/321)× 298 K

    = 133.68 atm

   = 134 atm

Therefore, the new pressure will be 134 atm.

Which type of crust combination CANNOT undergo subduction?
nordsb [41]

Answer:

the correct answer is B

Explanation:

Subduction: they present if or if two Convergent edges or subduction zones (destructive edges). Where two plates collide, due to having movements with opposite directions, the denser one sinks below the less dense one along what is known as the subduction zone; the subducting plate goes into the mantle, heating up and partially melting generating magma that rises to the surface. A subduction zone is characterized by deformation, volcanism, mountain formation, metamorphism, seismic activity, and significant mineral deposits.

This phenomenon occurs between oceanic plates or between a continental and an oceanic plate, since when there is a difference in density they subduct.

In the event that the edges of two continental plates collide, it would be OBDUCTION, which is another phenomenon other than subduction. mantle does not produce the correct subduction process, as the movement must be absorbed in some way, this is carried out by vertically deforming both plates, which are joined by a suture area, forming an inner mountainous belt and Suffering, in addition, numerous earthquakes. This process is very important, since it is the one that has given rise to the highest mountain ranges on Earth and is a very active process at present (Ex: Los Alpes, Los Montes Urales and Montes Himalaya).
