<h3>Explanation</h3>
Helium is a noble gas. The interaction between two helium molecules is rather weak, which makes the gas rather "ideal."
Consider the ideal gas law:
,
where
is the pressure of the gas,
is the volume of the gas,
is the number of gas particles in the gas,
is the ideal gas constant, and
is the absolute temperature of the gas in degrees Kelvins.
The question is asking for the final volume
of the gas. Rearrange the ideal gas equation for volume:
.
Both the temperature of the gas,
, and the pressure on the gas changed in this process. To find the new volume of the gas, change one variable at a time.
Start with the absolute temperature of the gas:
,
.
The volume of the gas is proportional to its temperature if both
and
stay constant.
won't change unless the balloon leaks, and- consider
to be constant, for calculations that include
.
.
Now, keep the temperature at
and change the pressure on the gas:
,
.
The volume of the gas is proportional to the reciprocal of its absolute temperature
if both
and
stays constant. In other words,
(3 sig. fig. as in the question.).
See if you get the same result if you hold
constant, change
, and then move on to change
.

Answer:
Fermentation, chemical process by which molecules such as glucose are broken down anaerobically. More broadly, fermentation is the foaming that occurs during the manufacture of wine and beer, a process at least 10,000 years old. The frothing results from the evolution of carbon dioxide gas, though this was not recognized until the 17th century.
