Question

The coefficient of apparent expansion of a liquid is 10 ^ - 1 * P * C and the coefficient of cubical expansion is 2*10^ -4 ^ C then what is the coefficient of real expansion of the liquid? (A) 1*10^ -4 ^ C (B) 3*10^ -4 ^ 0 C (C) 6*10^ -4 /^ 0 C (D) 8*10^ -4 ^ C​

Answer 1

Answer:

Coefficient of real expansion of the liquid is defined as the ratio of real change in the volume to its original volume per 1 o C rise in temperature. Its SI unit is " per oC " or " oC −1" or " K −1 ".
