SUMMARY
The discussion focuses on calculating the percentage change in density of lead when its temperature is raised from 0°C to 100°C, utilizing the equation ΔV = Vi βΔT. Participants clarify the distinction between β (compressibility) and α (thermal expansion coefficient), emphasizing that for volumetric expansion, the relationship αv ≅ 3*αL must be applied. The density of lead at 0°C is specified as 11,300 kg/m³, which is crucial for accurate calculations.
