If 9.5 atms of pressure were increased to 25 atms of pressure, what would be the final volume
nordsb [41]

Answer:

The final volume of the gas is 36.1 L.

Explanation:

Given:

Initial pressure of the gas is, P_1=9.5\ atm

Final pressure of the gas is, P_2=25\ atm

Initial volume of the gas is, V_1=95\ L

Final volume of the gas is, V_2=?

Here, we shall use Boyle's Law which states that for a process under constant temperature, the pressure of the gas changes inversely with the change in volume.

Here, the pressure is increased. So, the volume of the gas is decreased.

Therefore, as per Boyle's Law:

P_1V_1=P_2V_2\\9.5\times 95=25V_2\\902.5=25V_2\\V_2=\frac{902.5}{25}\\V_2=36.1\ L

So, the final volume of the gas is 36.1 L.

1. Name two organisms that are competing for energy and explain HOW they compete.​
lutik1710 [3]

Answer:

There could be a few answers for this question, but my answer would be two different plants. Maybe a bush on the ground fighting for the energy of the sun with a tall tree. Leaves collect the energy from the sun and convert it to energy usable for the plant. a bush on the ground would be fighting for the sunlight with a tall tree.
