A balloon has a pressure of 104.5 kpa and a volume of 3.4L. If the pressure is reduced to 42.7 kpa, what will the volume change to?

The answer to your question is 8,32 L

Explanation:

Data

Pressure 1 = 104.5 kPa

Volume 1 = 3.4 L

Pressure 2 = 42.7 kPa

Volume 2 = ?

Formula

- To solve this problem use the Boyle's law.

       P1V1 = P2V2

- Solve for V2

       V2 = P1V1 / P2

- Substitution

       V2 = (104.5)(3.4) / 42.7

-Simplification

       V2 = 355.3 / 42.7

- Result

        V2 = 8.32 L            

The new volume is 8.3 L

Explanation:

Step 1: Data given

Initial pressure of balloon = 104.5 kPa = 1.0313348 atm

Volume of the balloon is 3.4 L

The pressure is reduced to 42.7 kPa = 0.4214162 atm

Step 2: Calculate the new volume

p1*V1 = p2 *V2

⇒p1 = the initial pressure in the balloon = 1.0313348 atm

⇒V1 = the initial volume = 3.4 L

⇒p2 = the reduced pressure = 0.4214162 atm

⇒V2 = the new volume

1.0313348 atm * 3.4 L = 0.4214162 * V2

V2 = 8.3 L

The new volume is 8.3 L

the ozone layer acts as a filter for the shorter wavelength and highly hazardous ultraviolet radiation (uvr) from the sun, protecting life on earth from its potentially harmful effects. when the sky is clear, there is an inverse relationship between stratospheric ozone and solar uvr measured at the earth's surface.
