A plastic bottle contains 32.5 L of gas at a pressure of 45.7 kPa and
Monica [59]

Answer:

Final pressure, P2 = 362.26 kPa

Explanation:

Given the following data;

Initial volume = 32.5 Liters

Initial pressure = 45.7 kPa

Final volume = 4.1 Liters

To find the final pressure, we would use Boyle's law;

Boyles states that when the temperature of an ideal gas is kept constant, the pressure of the gas is inversely proportional to the volume occupied by the gas.

Mathematically, Boyles law is given by;

PV = K

P_{1}V_{1} = P_{2}V_{2}

Substituting into the equation, we have;

45.7 * 32.5 = P_{2} * 4.1

1485.25 = 4.1P_{2}

P_{2} = \frac {1485.25}{4.1}

P_{2} = 362.26

Final pressure, P2 = 362.26 kPa

Why socialist government turn authoritarian
Orlov [11]

The reason why socialist governments often turn authoritarian are:

  • Having too much power eventually corrupts the holder.
  • When resistance builds, they try to suppress it because they feel socialism is the best way.

<h3>Why does socialism sometimes become authoritarianism?</h3>

Socialist governments tend to have too much power vested in the Executive in order to properly plan the economy. As a result, they often get corrupted because their power is inhibited.

When this corruption leads to inefficiency, authoritarianism is introduced to ensure that the citizens cannot overthrow the government which wants to keep power.

Tanya [424]
False the process is reversed. Photosystem ll happens before photosystem l. I know that's weird but it's true. In photosystem ll which happens first it makes the energy carriers for ATP Synthase to happen in Photosystem l which is the next phase. Hope this helped!
