What is change in volume of an iron sphere of volume 500 ~cm ^3 , when it is heated from 0^ C to ( _ Iron =12 10^ -6 / ^ C ) ?

Options

  1. A1.8 ~cm ^3
  2. B2 ~cm ^3
  3. C1.4 ~cm ^2
  4. D3 ~cm ^3

Correct answer

A. 1.8 ~cm ^3

Step-by-step solution

aligned & Change in Vol. Original Vol. = Coe. of vol. expansion temp change & V=V (3 _ Iron ) ( T) & V=500 ~cm ^3 [3 (12 10^ -6 / ^ C ) ] (100^ C ) & V=500 3.6 10⁻³ ~cm ^3=1.8 ~cm ^3 aligned
