Given:
A balloon occupies a volume of 2.0 L at 40°C.
To find:
The volume was occupied at 30°C.
Solution:
According to the ideal gas law, we know that PV=nRT
At constant composition and pressure, volume is proportional to T.
Thus we can write-
V1T2=V2T1
Where V1 is the initial volume=2.0L.
V2 is the final volume=xL.
T1 is the initial temperature is equal to 40+273=313K.
T2 is the final temperature is equal to 30+273=303K.
Thus we can write-
The balloon occupies a volume of 1.94L.
Hence the correct option is B.
