A balloon is filled with helium gas has a volume of 1.0 L at a pressure of 1.0 atm. The
balloon is released and reaches an altitude where the pressure is now 0.4 atm. What is the
new volume of the balloon at this altitude assuming the air temperature has not changed?

Answer:

2.5 L

Explanation:

The new volume of the balloon can be found by using the formula for Boyle's law which is

[tex]P_1V_1 = P_2V_2[/tex]

Since we are finding the new volume

[tex]V_2 = \frac{P_1V_1}{P_2} \\[/tex]

From the question we have

[tex]V_2 = \frac{1 \times 1}{0.4} = \frac{1}{0.4} \\ = 2.5[/tex]

We have the final answer as

2.5 L
