Lead has a density of 11300 kg/m^3 at 0 degrees celcius. What is the density of lead at 90 degrees celcius?

  • Physics -

    You will find the volumetric thermal expansion coefficient of lead is 87*10^-6 C^-1
    Multiply that by 90 C for the relative volume increase factor,
    DeltaV/V = 0.0078

    Add that to 1 and take the reciprocal

    Density(90)/Density(0) = 0.9922

    Finally, multiply that by the density at 0 C
