Answer:
Pressure = 47.1kPa
Explanation:
V1 = 5.0L
P1 = 94.2kPa = 94.2*10³Pa
V2 = 2V1 = 2 * 5.0 = 10L
P2 = ?
To solve this question, we'll have to use Boyle's law which states that the volume of a fixed mass of gas is inversely proportional to its pressure provided that temperature remains constant
Mathematically,
V = k/P, k = PV
P1V1 = P2V2 = P3V3=........=PnVn
P1V1 = P2V2
Solve for P2
P2 = (P1 * V1) / V2
P2 = (94.2*10³ * 5.0) / 10
P2 = 47100Pa
P2 = 47.1kPa
The new pressure of the gas is 47.1kPa
