A toy balloon contains 0.75 L of helium at a pressure of 101 kPa. The balloon rises until the pressure on the balloon is 85 kPa. What is the balloon's volume?

Respuesta :

The answer is 0.89 L

Explanation:

The new volume 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{101000 \times 0.75}{85000} = \frac{75750}{85000} \\ = 0.89117647...[/tex]

We have the final answer as

0.89 L

Hope this helps you
