Question

A balloon filled with helium has a volume of 30.0 L at a pressure of 0.9 atm and a temperature of 15.0oC. What will the volume of the balloon be if the temperature is increased by 80oC and the pressure remains constant?

Answer 1

The volume of the balloon 'll be 36.7L

Step-by-step explanation:

If the pressure remains constant and the temperature was increased, the volume will be increased too.

At constant pressure, the volume varies directly proportional to the asbolute T ° (Charles-Gay Lussac)

V₁ / T₁ = V₂ / T₂

30L / 288K = V₂ / 353K

(30L / 288K) . 353K = V₂

36.7L = V₂
