SUMMARY
The discussion focuses on calculating the minimum energy required to melt 130g of silver at an initial temperature of 15 degrees Celsius. The correct formula to use is Q = mC(Tf - Ti) + mHf, where m is mass, C is specific heat, Tf is the final temperature, Ti is the initial temperature, and Hf is the latent heat of fusion for silver. It is emphasized that temperature differences can be expressed in either Celsius or Kelvin without conversion, but care must be taken to ensure consistent units for specific heat and latent heat of fusion.
