Question

${\gamma }_r$ is coefficient of real expansion of a liquid, ${\gamma }_a$ is coefficient of apparent expansion of a liquid and ${\gamma }_g$ is coefficient of cubical expansion of the container then the correct relation is :

• A. ${\gamma }_r={\gamma }_a\times {\gamma }_g$
• B. ${\gamma }_r={\gamma }_a÷{\gamma }_g$
• C. ${\gamma }_r={\gamma }_a-{\gamma }_g$
• D. ${\gamma }_r={\gamma }_a+{\gamma }_g$

Answer 1

Answer: (D)

The relation between ${\gamma }_r,{\gamma }_{a}and{\gamma }_g$ is ${\gamma }_r={\gamma }_a+{\gamma }_g$

where,${\gamma }_r,{\gamma }_{a}and{\gamma }_g$ are coefficient of real expansion of a liquid, coefficient of apparent expansion of a liquid and coefficient of cubical expansion of the container respectively.
