The relation between the coefficient of real expansion $(\gamma_r)$ and coefficient of apparent expansion $(\gamma_a)$ of a liquid and the coefficient of linear expansion $(\alpha_g)$ of the material of the container is:
- A$\gamma_r = \alpha_g + \gamma_a$
- B$\gamma_r = \alpha_g + 3 \gamma_a$
- C$\gamma_r = 3 \alpha_g + \gamma_a$
- D$\gamma_r = 3(\alpha_g + \gamma_a)$
