If I have 45 liters of helium in a balloon at 25 degress celcius and increase the tempurate to 55 degrees celcius what will the new volume be?
This is a problem involving the temperature-volume relationship of gases, which is represented by Charles's law:
Now, rearrange the equation to solve for
and plug in the known values:
(The decimal place is present to emphasize there are two significant figures, otherwise it's arbitrary whether you're using one or two.)
