Ответ:
The Ideal Gas Law states that PV=nRT where P is pressure, V is volume, n is number of molecules, R is the gas constant and T is the temp.
As the number of molecules does not change and pressure does not change, we move the constants to one side: V/T=nR/P=constant.
We get V1/T1=V2/T2
Temp should be in K so T1=-50C+273=223K
T2=35C+273=308K
V2=T2*V1/T1=308*550/223
=759.64mL
Ответ:
Air is less dense on a mountaintop than at sea level.
Air pressure is lower at low altitudes.
As you climb a mountain, air pressure increases.
More force pushes on the air at the bottom of an air column.
As you descend a mountain, air molecules are closer together.
