Ahelium balloon is filled to a volume of 2.88 x 103 l at 722 mm hg and 19â°c. when the balloon is released, it rises to an altitude where the pressure and temperature are 339 mm hg and -55oc, respectively. what is the volume of the balloon (in l)

V₂=4.57 x 10³ L

Explanation:

Given that

V₁= 2.88 x 10³ L

P₁=722 mm  Hg

T₁ = 19°C

T₁ =292 K

P₂=339 mm Hg

T₂= - 55°C

T₂=218 K

Lets take final volume = V₂

We know that ideal gas equation

PV = m R T

By applying mass conservation

V₂=4.57 x 10³ L

Therefore volume will be 4.57 x 10³ L
