A chemistry poem for Robert Burns Day

From the Journal of Chemical Education, 2007, vol. 84,  p.605.  More information about the poem is in the article itself.

This poem’s a tribute to Robert Burns
That praises Scottish chemists and their works in four turns.
I hope that you’ve all lowered the bar enough,
I’m a chem teacher, not a poet, but you might learn some stuff.

Joseph Black discovered carbon dioxide.
Without this gas our plants would have died.
Produced when carbon compounds burn,
Too much in the air is a global warming concern.
Black found latent heat would suffice
To explain boiling of water and melting of ice.

James Dewar developed his namesake flask
And for liquid gases it was up to the task.
It’s used today in your Thermos bottle…
…Your eyes are glazing over, so I won’t dawdle.

If I had to choose, if I had to guess,
I think Sir William Ramsay was among the best.
He had English colleagues, which isn’t so wrong.
We can be quite productive when we all get along.
Argon, neon, and others with like labels,
He added noble gases to our periodic tables.
Scottish pride likely hit new highs
When in 1904 he earned a Nobel Prize.

Finally there was Thomas Graham (not of cracker fame)
Who developed the law that now bears his name,
Which says that the rates of effusion of gases
Are inversely proportional to the square roots of their molar masses.
(We even cover this in our General Chemistry classes!)
We have students use this law in gas analysis,
But neglect to mention his gains with dialysis.
Over one million lives have been spared in this way.
His use of the word “colloid” remains to this day.
The word (meaning “glue-like”) can describe gel behavior
            Nanotechnology helps keep colloids in favor.

Four Scottish chemists whose fame involved gases.
Be thankful this poem is shorter than my classes!
Speaking of gases, if you think my air’s gone too far,
Note I wrote much of this in a car!
