Question

You place a balloon in a closed chamber at standard temperature and pressure (STP). You halve the chamber pressure. What happens to the balloon? Explain how you got your answer.
a). It doubles in volume.
b). It decreases to one-half of its original volume.
c). It expands to four times its original volume.
d). It stays the same volume

Answer 1

The answer to the question stated above would be a) it doubles in volume. This is because the chamber pressure is inversely proportional to the volume. Thus, if you decrease the pressure by half, then the volume of the balloon - since it's inversely proportional - is multiplied by two. 

Answer 2

Answer:

a). It doubles in volume.
