How does extreme pressure affect the volume occupied by a real gas compared to the predictions of the ideal gas law?

a. the true volume of the gas will be higher than predicted by the ideal gas law because the volume of the actual particles is more significant under high pressure.

b. the true volume of the gas will be higher than predicted by the ideal gas law because the attraction between the particles is weaker under high pressure.

c. the true volume of the gas will be lower than predicted by the ideal gas law because the volume of the actual particles is more significant under high pressure.

d. the true volume of the gas will be lower than predicted by the ideal gas law because the attraction between the particles is weaker under high pressure.

The correct answer is A.

Explanation:

Properties of ideal gases have different volumes under very high pressure. These gases take up additional volume when there is high pressure exerted, and the predicted volume of these gases will end up being smaller than the actual values of the gas volumes. Therefore, the true volume of the gases will be higher than the low ones that were predicted, giving your answer A.

answer: the figure is attached herewith.

step-by-step explanation:   we are given to sketch a unit circle and label the terminal points corresponding to

in the attached figure, we have drawn a unit circle, with centre at o(0,0) and radius 1 unit. we have labelled the points a, b, c, d and e corresponding to the angles below

∠aox = 60°,

∠box = 120°,

∠cox = 180°,

∠dox = 240°,

∠eox = 300°.

and the coordinates are a(0.5,1), b(-0.5,1), c(-1,0), d(-0.5,-1) and e(0.5,-1).

thus, the answer is complete.
