Question

What volume will a balloon occupy at 1.0 atm, if the balloon has a volume of 7.6 l at 3.8 atm?

Answer 1

From the Boyle's law, it is clear that volume is inversely proportional to pressure. Thus it is prudent to say that, P1V1=P2V2
From the question above,
P1=1atm
P2=3.8atm
V1=?
V2=7.6L
Hence, 1*V1=3.8atm*7.6L
V1=28.88L

Answer 2

Answer: The final volume of balloon is 28.88 L

Step-by-step explanation:

To calculate the new volume, we use the equation given by Boyle's law. This law states that pressure is inversely proportional to the volume of the gas at constant temperature.

The equation given by this law is:

`P_1V_1=P_2V_2`

where,

`P_1\text{ and }V_1` are initial pressure and volume.

`P_2\text{ and }V_2` are final pressure and volume.

We are given:

`P_1=3.8atm\\V_1=7.6L\\P_2=1.0atm\\V_2=?L`

Putting values in above equation, we get:

`3.8atm* 7.6L=1.0atm* V_2\\\\V_2=(3.80* 7.6)/(1)=28.88L`

Hence, the final volume of balloon is 28.88 L
