3. Oxygen gas inside a 1.5 L gas tank has a pressure of 0.95 atm. Provided that the temperature
remains constant, how much pressure is ne
eded to reduce its volume by 72?​

1.9 atm

Explanation:

Using Boyle's law :

Pressure is inversely proportional to volume Given that temperature and mass remains constant.

Mathematically ;

P1V1 = P2V2

P1 = 0.95 ; V1 = 1.5L; P2 = ? ; V2 = 1.5 - (1/2*1.5) = 0.75 L

P1V1 = P2V2

0.95 * 1.5 = P2 * 0.75

1.425 = 0.75P2

P2 = 1.425 / 0.75

P2 = 1.9

P2 = 1.9 atm

the excerpt from chapter 2 of "animal farm", by george orwell that is an example of foreshadowing is "these three (snowball, napoleon, and squealer) had elaborated old major's teachings into a complete system of thought to which they gave the name of animalism." animal farm is an allegory of how czarist russia developed into communist russia with all its corruption. old major's teachings represent marx's theories turned into communism, animalism, by the three pigs. this foreshadows the oppression and corruption that will follow this revolt.
