A balloon contains 2.27 ~L air and has a pressure of 1.013 10^5 Nm ⁻² . The balloon rises to a certain height and expands to volume of 4540 ~mL . What is the final pressure of air in balloon?

Options

  1. A2.026 10^2 Nm ⁻²
  2. B5.065 10^4 Nm ⁻²
  3. C4.540 10^4 Nm ⁻²
  4. D5.065 10⁻⁴ Nm ⁻²

Correct answer

B. 5.065 10^4 Nm ⁻²

Step-by-step solution

aligned & P ₁ ~V ₁= P ₂ ~V ₂ & 1.013 10^5 2.27= P ₂ 4.540 & P ₂=5.065 10^4 Nm ⁻² aligned
