Answer:
e) 0.099
Explanation:
For an adiabatic expansion:
where
P1 is the initial pressure
P2 is the final pressure
V1 is the initial volume
V2 is the final volume
is the adiabatic index (which is
for an ideal monoatomic gas
In this problem, we have
since the volume increases by a factor 4
We can re-write the equation to find by what factor the pressure changes:
