Hello guys,
I've only recently started my ATPL integrated course and need some help. We've been going on in class that temperature and pressure decrease as altitude increases but the density also decreases. Apparently the decrease in density doesn't have anything to do with the decrease in temperature which was what I would expect because: p=m/V Volume depends on pressure and temperature therefore the density depends on pressure and temperature.
So my question is why does density decrease with altitude?
Also another question.
Q. If you're in a hot atmosphere:
a) The pressure is less than ISA.
b) The pressure is more than ISA.
c) The density is less than ISA.
d) The density is more than ISA.
Please explain the answer.
Thanks a lot.
