Question

A lead bullet has volume of 25 cm ³ at 0°C, and 25.21 cm ³ at 90 °C . find the volumetric expansion coefficient of lead.

no army I don't know her ​

Answer 1

Answer:

$\huge\mathcal\red{your \: answer \: is \: here}$

By definition, coefficient of volume expansion of lead, γ=Vt−V0V0t

Given, Vt−V0=0.021cm3,V0=2.5cm3 and t=98∘C

∴ γ=0.0212.5×98=85.7×10−6∘C−1

∴ Coefficient of linear expansion of lead,

α=γ3=8.57×10−63=2.86×10−6∘C−1.
