Questions
In an adiabatic expansion of air (assume it a mixture of N2 and O2), the volume increases by 5% the percentage change in pressure is:
a
3%
b
4%
c
6%
d
7%
detailed solution
Correct option is D
PVγ= constant P1×105V100γ= Constant ∴P1P×105100γ=1 or P1P=10010575 γ for N2 or O2=7/5 P1=0.93P ∴7% decreaseinpressure.Talk to our academic expert!
