Final answer:
To calculate heat transfer for melting and increasing the temperature of lead, the specific heat capacity and latent heat of fusion for lead are required. These two quantities are used to compute the heat for temperature rise and phase change, respectively.
Step-by-step explanation:
To determine how much heat transfer is needed to melt a specific mass of lead and raise its temperature, we use the following steps:
- Calculate the heat needed to increase the temperature of lead to its melting point.
- Add to this the heat needed to melt the lead, which involves using the latent heat of fusion.
We'll use specific heat capacity and latent heat of fusion data for lead which can be found in tables of thermodynamic properties. For lead, the specific heat capacity (c) is generally about 0.128 J/g°C, and the latent heat of fusion (Lf) is roughly 24.7 kJ/mol. Since the question does not provide these values, you would need to confirm them from a reliable source.
