@ A weather balloon contains 59.5L of helium
ICH sea level, where the atmospheric pressure
lis 101. 3 kPa. The balloon is released from a 4.000-
Im moutaintop where the pressure is 61.7 kPa
what volume will the balloon have eat that
altitude?

Answer 1

V₂ = 97.7 L

Step-by-step explanation:

Given data:

Initial volume of balloon = 59.5 L

Initial pressure = 101.3 Kpa

Final pressure = 61.7 kpa

Final volume = ?

Solution:

Formula:

P₁V₁ = P₂V₂

P₁ = Initial pressure

V₁ = Initial volume

P₂ = Final pressure

V₂ =Final volume

Now we will put the values in formula.

P₁V₁ = P₂V₂

101.3 kpa × 59.5 L = 61.7 kpa × V₂

V₂ = 6027.35 kpa.L /61.7 kpa

V₂ = 97.7 L
