The relation between the coefficient of real expansion ( _r ) and coefficient of apparent expansion ( _a ) of a liquid and the coefficient of linear expansion ( _g ) of the material of the container is

Options

  1. A_r= _g+ _a
  2. B_r= _g+3 _a
  3. C_r=3 _g+ _a
  4. D_r=3 ( _g+ _a )

Correct answer

C. _r=3 _g+ _a

Step-by-step solution

Coefficient of real expansion = coefficient of apparent expansion + coefficient of expansion of material of container but _r= _a+ _g So, =3 _r= _a+3 _g
