A glass flask of volume 400cm is just filled with mercury at 0 degree

A glass flask of volume 400 cm³ is just filled with mercury at 0°C. How much mercury will  overflow when the temperature of the system rises to 80°C.

The volume of mercury that overflow is 5.376 cm³

Given

volume of glass = 400 cm³

Δt=80 °C - 0 °C = 80

Required

overflow volume

Solution

With an increase in the temperature of the substance, objects can expand. This expansion includes volume expansion.

Can be formulated

Find volume expansion of glass and mercury

Overflow :

ΔV mercury - ΔV glass : 5.76-0.384 = 5.376 cm³
