Utilizados em diversas áreas de pesquisa, balões estratosféricos são lançados com seu invólucro impermeável parcialmente cheio de gás, para que possam suportar grande expansão à medida em que se elevam na atmosfera. 
Um balão, lançado ao nível do mar, contém gás hélio à temperatura de 27 °C, ocupando um volume inicial Vi . O balão sobe e atinge uma altitude superior a 35 km, onde a pressão do ar é 0,005 vezes a pressão ao nível do mar e a temperatura é -23 °C.
Considerando que o gás hélio se comporte como um gás ideal, qual é, aproximadamente, a razão Vf /Vi , entre os volumes final Vf e inicial Vi ?

The complex linguistic universe of

Game of Thrones
1.Game of Thrones has garnered 38 Emmy
2.awards for its portrayal of a world of sex,
3.violence and politics so real that some viewers
4.could imagine moving there. Part of that detail
5.has been the creation of the richest linguistic
6.universe since J.R.R. Tolkien’s Middle Earth.
7.In the field of language-creation for fictional
8.worlds, there is Tolkien, and there is everybody
9.else. But David Peterson, the language-smith
10.of Game of Thrones , comes a close second for
11.the amount of thought put into its two
12.languages, Dothraki and Valyrian. The interest
13.in these tongues is such that a textbook for
14.learning Dothraki has been published, while
15.Duolingo, a popular online language-learning
16.platform, now offers a course in High Valyrian.
17.Inspired by fictional languages such as those
18.in the Star Wars films and with a master’s
19.degree in linguistics, Peterson made Dothraki
20.and Valyrian as rich and realistic as possible.
21.Creating words is the easy part; anyone can
22.string together nonsense syllables. But
23.Peterson, like Tolkien, took the trouble to give
24his words etymologies and cousins, so that
25.the word for “feud” is related to the words
26.“blood” and “fight”. To make the languages
27.pronounceable but clearly foreign, he put
28.non-English sounds in high-frequency words
29.(like khaleesi , or queen), put the stress in
30.typically non-English places, and had words
31.begin with combinations of sounds that are
32.impossible in English, like hr .
33.Armed with a knowledge of common linguistic
34.sound changes, he gives his languages the
35kinds of irregularities and disorder that arise in
36.the real world: High Valyrian’s obar
37(“curve”) becomes Astapori Valyrian’s uvor .
38.Words’ meanings—as in real life—drift, too,
39.giving the system more realistic messiness.
40.Languages also play a prominent role in the
41.storyline. Dothraki is the guttural language of
42.a horse-borne warrior nation, but high-born
43.Daenerys Targaryen does not look down on it;
44.methodically learning it is key to her rise.
45.Tyrion Lannister is left to administer the city
46.of Mereen despite his ropy command of
47.Valyrian, leading to some comic moments.
48.And a prophecy of a future hero acquires new
49.meaning when an interpreter explains that the
50.word in question is ambiguous in Valyrian—it
51.could be “prince” or “princess”.
52.It might seem odd that a highly sexist society
53.like the one of Game of Thrones would have
54.languages where sex roles were not clearly
55.marked, but languages are not always perfect
56.vehicles for a culture. Random change can
57.leave them with too many words for one
58.concept, and not enough for another. In this
59.way, the flawed nature of language reflects
60.the foibles of flawed humans and the
61.imperfect worlds they strive to create.

........ September 11, 2001, at 8:46 A.M., a
hijacked airliner crashed into the north tower
of the World Trade Center in New York. At
9:03 A.M. a second plane crashed into the
south tower. The resulting infernos caused
the buildings to , the south tower
after burning for an hour and two minutes, the
north tower twenty-three minutes after
that. The attacks were masterminded by
Osama bin Laden in an attempt to intimidate
the United States and unite Muslims for a
restoration of the caliphate.
9/11, as the happenings of that day are now
called, has set off debates on a vast array of
topics. But I would like to explore a lesserknown
debate triggered by it. Exactly how
many events took place in New York on that
morning ........ September?
It could be argued that the answer is one.
The attacks on the two buildings were part of
a single plan conceived by one man in service
of a single agenda. They unfolded ........ a few
minutes and yards of each other, targeting
the parts of a complex with a single name,
design, and owner. And they launched a
single chain of military and political events in
their aftermath.
Or it could be argued that the answer is two.
The towers were distinct collections of glass
and steel separated by an expanse of space,
and they were hit at different times and went
out of existence at different times. The
amateur video that showed the second plane
closing in on the south tower as the north
tower billowed with smoke makes the twoness
unmistakable: while one event was frozen in
the past, the other loomed in the future.
The gravity of 9/11 would seem to make this
discussion frivolous to the point of impudence,
a matter of mere "semantics," as we say, with
its implication of splitting hairs. But the
relation of language to our inner and outer
worlds is a matter of intellectual fascination
and real-world importance.
______ "importance" is often hard to
quantify, ........ this case I can put an exact
value on it: 3,5 billion dollars. That was the
sum in a legal dispute for the insurance
payout to Larry Silverstein, the leaseholder of
the World Trade Center site. Silverstein’s
insurance policies stipulated a maximum
reimbursement for each destructive "event."
If 9/11 comprised a single event, he stood to
receive 3,5 billion dollars; if two, he stood to
receive 7 billion. In the trials, the attorneys
disputed the applicable meaning of the term
event. The lawyers for the leaseholder defined
it in physical terms (two s); those for
the insurance companies defined it in mental
terms (one plot). There is nothing "mere"
about semantics!

Thought . New York: Penguin, 2007. p. 1-2.

I - the south tower after having been burning for an hour and two minutes 
II - the south tower after it was burning for an hour and two minutes 
III- the south tower after it had been burning for an hour and two minutes
