Answer:

The correct answer is 3.6 L

Explanation:

According to the gases Boyle's law, the relation between the volume and  the pressure of a gas at constant temperature is given by the following mathematical expression:

Pi x Vi = Pf x Vf

Where Pi and Vi are the <u>initial </u>pressure and volume of the gas whereas Pf and Vf are the <u>final</u> pressure and volume, respectively.

In this problem we have:

Vi = 18.0 L

Pi= 902 Torr

Pf= 4510 Torr

The final volume (Vf) will be:

Vf = (Pi x Vi)/Pf = (902 Torr x 18.0 L)/4510 Torr= 3.6 L

From the result, we can see that if the pressure increases, the volume of the gas decreases.

Zanzabum

Answer:

Carbon dioxide is moving out of the living things.

Explanation:

The food materials eaten by living things contain carbon in the form of complex organic matter. When living things feed, they ingest this complex organic material into their bodies.

During the process of digestion, this complex organic material is broken down to give glucose. Glucose is the energy molecule in living things. Excess glucose in the body is stored as glycogen.

During cellular respiration, glucose is broken down to release carbon dioxide. Hence, at night when the giraffe has stopped eating, cellular respiration continues to occur and carbon dioxide is released, that is, carbon dioxide continues to move out of living things at night.

Round to 4 significant figures.<br> 0.007062
lapo4ka [179]

Answer:

Hey there!

This is already rounded to four significant figures!

Zeroes after the decimal but before the 7 don't count, and 7, 0, 6, and 2 count as significant figures.

So, the answer would be 0.007062.

Let me know if this helps :)
