Answer 1

can i get some help plzz

Answer 2

Ideal gas equation again :)
imprint this equation in your mind.
\[\Huge pV=nRT\]
Using the equation say what the answer is! :)

Answer 3

im confuesed

Answer 4

Okay.
Lets try solve for the volume and see what we can conclude:
\[\Large pV=nRT \to v=\frac{ nRT }{ p }\]
Now what happens if we increase \(p\)? If \(p\) increase the denominator increase, and if the denominator increase the whole fraction is getting lower, so if p increase v decrease.

Can you follow that?
