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
Lead is a soft, dense metal with melting point of 328°C, a heat of
fusion of 5.5 kcal/kg, and a specific heat of 0.028 kcal/(kg.°C).

sample of lead with an initial temperature of 46.2°C?
Solid honorite has a melting temperature of 261.15 K, and a heat capacity of 457 J/kgK. When it is liquid, its heat capacity is 575 J/kgK. The latent heat for the transition
from solid to liquid is 15300 J/kg.
Liquid odium has a freezing temperature of 330.2 K and a heat capacity of 428.7 J/kgK. When solid, its heat capacity is 332.7 J/kgK. The latent heat for the transition from
solid to liquid is 10700 J/kg.
