Posted by Kim on Tuesday, March 30, 2010 at 10:11pm.

How much energy is needed to melt 0.225 kg of lead so that it can be used to make a lead sinker for fishing? The sample has an initial temperature of 27.3 degrees celsius and is poured in the mold immediately after it has melted.
Not sure if this is relevant to finding the answer but just incase:
Melting point of lead: 327.3 degrees celsius
Boiling point of lead: 1745 degrees celsius
Latent head of fusion for lead: 2.45 x 10^4 J/kg
Latent heat of vaporization for lead: 1.14 x 10^7 J/kg
