Question

A helium-filled weather balloon has a volume of 595 L at 14.9°C and 751 mmHg. It is released and rises to an altitude of 5.55 km, where the pressure is 451 mmHg and the temperature is –17.1°C. The volume of the balloon at this altitude is ___ L.

Answer 1

T °C +213.15 Initial conditims. v=595L T = (14.9+273.15 JK T = 288.05k P-7 Si mmHg altitude of 5.55km Final conditions V = ? T2 = (17.1 +273.15) T2 = 256.05k P₂ = 451 mmile Relation between por and T T PV, Tz =ų - TP2 = 751 mmHg) (595L) (256.05k) (288.05k ) (451 mm Hg) | 88 672 L = 1, 881 L = V2 rounded to three sig. fig.
