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

The row of energy in a grassland ecosystem is shown
bixtya [17]

The populations with the trophic levels that receive the least amount of the total energy from the grass would be Hognose snakes and owls.

<h3>Trophic Level</h3>

The higher we move up a trophic level, the lower the amount of energy transferred from the previous levels.

More precisely put, only about 10% of the total energy available at one trophic level is transferred to the next while the rest is lost as heat to the surrounding.

In this case, Hognose snakes and owls represent the two highest trophic levels in the ecosystem. Thus, their populations would receive the lowest amount of energy from the producer, the grass.
