A hot air balloon has volume of 2000 dm ^3 at 99^ C . What is the new volume if air in balloon cools to 80^ C ?

Options

  1. A2428.9 dm ^3
  2. B2656.9 dm ^3
  3. C2814.9 dm ^3
  4. D1897.8 dm ^3

Correct answer

D. 1897.8 dm ^3

Step-by-step solution

array ll & Using Charles' law, & V ₁ ~T ₁ = V ₂ ~T ₂ & 2000 dm ^3 372 ~K = V ₂ 353 ~K & V ₂= 2000 353 372 =1897.8 dm ^3 array
