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.
Aleksandr [31]

<h3>The answer is 0.89 L</h3>

Explanation:

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

P_1V_1 = P_2V_2

Since we are finding the new volume

V_2 =  \frac{P_1V_1}{P_2}  \\

From the question we have

V_2 =  \frac{101000 \times 0.75}{85000}  =  \frac{75750}{85000}  \\  = 0.89117647...

We have the final answer as

<h3>0.89 L</h3>

Hope this helps you
