Aliquid that is very volatile is also likely to show:
weak surface tension
high molecular weight
great resistance to flow
strong intermolecular forces

Option (a) is the correct answer.

Explanation:

Net downward force exerted at the surface of a liquid because of the presence of strong intermolecular forces in the molecules of a liquid present beneath the surface is known as surface tension.

Volatility is the property of a substance to convert readily into vapors or gaseous state from liquid state.

Hence, when molecules of a liquid has weak intermolecular forces then it will have weak surface tension. As a result, it can be converted into vapors easily.

Thus, we can conclude that a liquid that is very volatile is also likely to show weak surface tension.

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.
