r
)
and coefficient of apparent expansion
(
γ
a
)
of a liquid and the coefficient of linear expansion
(
α
g
)
of the material of the container is
γ
r
=
α
g
+

Solution:
Coefficient of real expansion
=
coefficient of apparent expansion
+ coefficient of expansion of
material of container
γ
r
=
γ
a
+
γ
g
but
γ
=
3
α
So,
γ
g
=
3
α
g
∴
γ
r
=
γ
a
+
3
α
