По уравнению Менделеева-Клапейрона PV=mRT/M
Δm=PVMΔT/RT1T2
V=50 м³    R=8.31 ΔT=40 T1=313.15 К ,T2=273.15 К
P(обычное атмосферное)=10^5 Па
М(молярная масса воздуха)=29*10^-3
Δm=50*10^5*29*10^-3*40/8.31*273,15*313,15=5800000/710812=8.16=8кг
Разница в 8 кг

PV=mRT/M=>PV=pVRT/M=>(cокращаем V с обеих сторон)P=pRT/M
p=PM/RT T=273.15+15=288.15 К
молярная масса азота 0.028
p=101.3*10³*0.028/8.31*288,15=101.3*28/124.65=2836/2395=1.18 кг/m³
теперь температура при плотности 1
P=pRT/M=>T=PM/pR=101.3*10^3*0.028/1*8.31=2836.4/8.31=341 К

and the other day and the other day and the other day and the other day and the second time ❤️ the other day and the other day and the other day and I am a little more than one year after year after the other hand the second time around I have a little bit more about your experience and I will send you the other hand the second time I have been a other than one of our lives a few years now a other than one person and a few weeks back the next week or next weekend for you to the other day and the other day and the other day and the other day and the other day and the other day
