Answer:
45kPa
Explanation:
P1 = 75kPa = 75,000Pa
V1 = 33L
V2 = 55L
P2 = ?
To solve this question, we'll have to apply Boyle's law which states that the volume of a fixed mass of gas is inversely proportional to its pressure provided its temperature remains constant
Mathematically,
V = k / P, k = PV
P1×V1 = P2×V2 = P3×V3=........=Pn×Vn
P1 × V1 = P2 × V2
P2 = (P1 × V1) / V2
P2 = (75000 × 33) / 55
P2 = 45000Pa
P2 = 45kPa
The final pressure of the gas is 45kPa
