Question: Calculate the minimum amount of energy, in joules, required to completely melt 135 g of silver initially at 28.0°C. The melting point of silver is at 962°C. Its specific heat capacity is 236 J/kg•K and its latent heat of fusion is 105 kJ/kg.
Show how you get the answer, so that I can better understand how to do it.
