lead has:

a specific heat of 130 J/kgK in solid form,

a specific heat of 130 J/kgK in liquid form,

a freezing temperature of 328 C

a boiling temperature of 1744 C,

a latent heat of fusion of 2.47e4 J/kg, and

a latent heat of vaporization of 8.67e5 J/kg

Step 1

Consider the lead of mass m having latent he...
