<em>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.</em>
<em />
The volume of mercury that overflow is 5.376 cm³
<h3>Further explanation</h3>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.

Find volume expansion of glass and mercury
- Glass(γ = 1.2.10⁻⁵ C⁻¹)
- Mercury(γ=1.8.10⁻⁴ C⁻¹)
Overflow :
ΔV mercury - ΔV glass : 5.76-0.384 = 5.376 cm³
