Why does the stainless steel keep the heat long?

Stainless steel retains heat well due to its dense molecular structure, which slows down the transfer of heat. Additionally, its relatively high specific heat capacity allows it to absorb and hold onto heat energy. However, it may not retain heat as effectively as materials like cast iron, which have better thermal conductivity. Overall, stainless steel provides a balance of durability and heat retention, making it a popular choice for cookware.
