Keeping temperature constant the pressure of 11.2 dm ^3 of a gas was increased from 105 kPa to 420 kPa . What is the new volume of gas?

Options

  1. A1.4 dm ^3
  2. B7.0 dm ^3
  3. C5.6 dm ^3
  4. D2.8 dm ^3

Correct answer

D. 2.8 dm ^3

Step-by-step solution

aligned & P ₁ ~V ₁= P ₂ ~V ₂ & 105 11.2=420 V ₂ & ~V ₂= 105 11.2 420 & 2.8 dm ^3 aligned
