Answer:

0.192cm^3

Real volume expansion of liquid = volume expansion of vessel+ apparent expansion of liquid

Apparent expansion of liquid is the amount of liquid or mercury which overflows when the temperature of system is raised.

apparent coefficient cubical expansion of liquid = real coefficient cubical expansion of liquid -coefficient of cubical expansion of glass

app = (1.8 x 10^-5 - 1.2 x 10^-5)°C-1

= 0.6 x10^-5°C-1

Apparent expansion of liquid = 400cm^3 x 0.6x10^-5°C-1 x (80-0)°c

=0.192 cm^3

As far as I guess.
