A helium-filled balloon has a volume of 1 m3 . As it rises in the earth's atmosphere, its volume expands. What will its new volume be (in m3) if its original temperature and pressure are 20C and 1 atm, and its final temperature and pressure are -40C and 0.1 atm?
a. 4
b. 6
c. 8
d. 10
e. 1.5
Question 2

a. 2
b. 1
c. 0.5
d. 0.1
