Question

A lead bullet has a volume of 25 cm³ at 0 °C, and 25.21 cm³ at 90 °C. Find the volumetric expansion coefficient of lead.

Answer 1

Data: V₁ = 25 cm³ , T₁ = 0 °C,

V₂ = 25.21 cm³ , T₂ = 90 °C

T₂ – T₁ = 90 °C – 0 °C = 90 °C β = ?

The volumetric expansion coefficient of lead is 9.333 × 10^-5 °C ^-1.
