Hi!(adsbygoogle = window.adsbygoogle || []).push({});

I have problem with this ...

A airmass with the volume 1200m^3 the presswure 101kPa and the temperature 288K moves vertical upwards. The pressure sinks to 80kPa and the temperature sinks to 270K.

Calculate the new pressure and I know how to use it

I take 101*1200/288 = 420 Is this right?

because v1*p1 /t1 = v2*p2/t2

And how do i make an equation of this?

and the second question is... how big volume would the airmass had in the normal conditions? Use that to calculate the airs mass...

And PLEASE no answer like this ... Use the Ideal Gas law... NO **** I had already found out that ...:surprised :surprised :surprised :surprised
