Question on: JAMB Physics - 2024
At a pressure of 105 Nm-2, a gas has a volume of 20 m3. Calculate the volume at 4 x 105 Nm-2 at constant temperature.
A
2m3
B
3m3
C
4m3
D
5m3

Correct Option: D
Using Boyle's Law (P₁V₁ = P₂V₂) for constant temperature:
- P₁ = 105 Nm-2
- V₁ = 20 m3
- P₂ = 4 x 105 Nm-2
- V₂ = ?
Apply the law:
V₂ = (P₁ * V₁) / P₂ = (105 * 20) / (4 x 105) = 20 / 4 = 5 m3
