A student is asked to draw a model that shows evaporation of a liquid. Balls will represent molecules, and arrows will represent motion. Longer arrows mean faster motion. Describe how you would show the spacing and motion of the molecules in the liquid state.
Describe how you would show the spacing and motion of the molecules in the gas state above the liquid surface.
Explain how you would show that evaporation is taking place, rather than condensation.

i believe the answer is d.

no options provided, here,but the answer to this question is often: a historian cites a japanese newspaper article published a year after the end of world war ii in order to draw conclusions about the effect of the war on the japanese economy.

clearly from the answer, the historian alludes to historical sources,and records to aid in analyzing and drawing conclusion on the effect of the war on the economy of japan.

it might be to see if the person answering knows what they are talking about other than just saying, "its b hope this ! : )" because they could say it then get the wrong answer because they only answered for the points.
