Question

A fixed amount of a gas occupies a volume of 1liter and exerts a pressure of 400 kPa on the walls of its container. What would be the pressure exerted by the gas if it is completely transferred into a new container having a volume of 3liter?​

Answer 1

Answer:

Ans = 133.33 KPa

Explanation:

since P1×V1 = P2×V2

THERFORE P2 = (P1 × V1) / V2

Answer 2

Answer:

Given,

Initial volume (V1) = 1L

Initial pressure (P1) = 400 kPa

Final volume (V2) = 3L

As per Boyle’s law, P1V1 = P2V2 ⇒ P2 = (P1V1)/V2

P2 = (1L * 400 kPa)/3L = 133.33 kPa

Therefore, the gas exerts a pressure of 133.33 kPa on the walls of the 3-liter.
