Which of the following correctly relates the real coefficient of volume expansion

\gamma_r

of a liquid to its apparent coefficient

\gamma_a

when contained in a glass vessel whose cubical expansion coefficient is

\gamma_c

? (a)

\gamma_r = \gamma_a - \gamma_c

(b)

\gamma_r = \gamma_a + \gamma_c

(c)

\gamma_r = \gamma_a\,\gamma_c

(d)

\gamma_r = \gamma_a + 3\gamma_c
