Asample of gas occupies a volume of 10.5 l when the pressure is 14.3 psi. use boyle’s law to calculate the pressure (psi) when the volume is reduced to 8.55l. show the calculation.

17.6psi

Explanation:

V1 = 10.5 L

P1 = 14.3 psi

V2 = 8.55L

P2 =?

P1V1 = P2V2

14.3 x 10.5 = P2 x 8.55

P2 = (14.3 x 10.5) / 8.55

P2 = 17.6psi

The final pressure is 17.56 psi

Explanation:

Step 1: Data given

Initial volume = 10.5 L

Initial pressure = 14.3 psi

Final volume = 8.55 L

Step 2: Calculate the new pressure

P1V1 = P2V2

⇒ P1 = The initial pressure = 14.3 psi

⇒ V1 = The initial volume = 10.5L

⇒ P2 = The final pressure = TO BE DETERMINED

⇒ V2 = The final volume = 8.55 L

14.3 * 10.5 = P2*8.55

P2 = 17.56 psi

The final pressure is 17.56 psi
