How is a cooker hob to magarine that is melting in a frying pan?

A cooker hob provides the heat necessary for cooking, similar to how a frying pan conducts that heat to melt margarine. When margarine is placed in the hot frying pan, it absorbs the heat from the pan, causing it to transition from a solid to a liquid state. This process illustrates the transfer of energy from the heat source (the hob) to the cooking surface (the frying pan) and then to the margarine. Ultimately, both the hob and the frying pan work together to facilitate the cooking process.
