Why does the bottom of a frying pan hot when you put it on stove?

When you place a frying pan on the stove, heat from the burner is transferred to the pan through conduction. Conduction is the transfer of heat through direct contact between two objects. In this case, the burner is transferring heat to the bottom of the pan. The metal of the pan conducts the heat well, which means that it quickly transfers the heat from the burner to the rest of the pan. This is why the bottom of the frying pan becomes hot when you put it on the stove.

The rate at which heat is transferred through conduction depends on several factors, including the temperature difference between the two objects, the area of contact between the two objects, and the thermal conductivity of the materials involved. In the case of a frying pan on a stove, the temperature difference between the burner and the pan is relatively high, the area of contact between the two objects is large, and the thermal conductivity of metal is relatively high. This all contributes to the fact that heat is transferred very quickly from the burner to the pan.

The bottom of the frying pan can become very hot when it is on the stove, so it is important to use caution when handling it. You should always use oven mitts or a pot holder when touching the bottom of a hot frying pan.
