The first: conduction from the solid heating coil
Convection
In actual fact stir fry is both conduction & convection, this is because the food is getting hot by conduction But then it is convection as you generally put water or something in it.

Both the flame heating the pan and the pan heating the water are examples of conduction. Convection is when the molecules of water heat other molecules of water.
Convection in a hot water bottle is the transfer of heat through the movement of the water inside the bottle as it heats up. Conduction is the transfer of heat through direct contact between the hot water in the bottle and the material of the bottle itself. Together, convection and conduction work to warm up the contents of the hot water bottle.

An example of convection without conduction would be the boiling of water in a pot. As the water heats up at the bottom of the pot, the hotter water rises to the top and cooler water moves downward to replace it. This creates a convection current that circulates the water, heating it evenly throughout the pot.
Gas heater & electric heater both are available.
This proess is called conduction. The other processes are convection and radiation. Convection is the transfer of energy through movement, such as boiling water. Radiation is the transfer of thermal energy through a medium or space, such as the sun heating the earth.

The movement of thermal energy is called heat transfer. Heat can be transferred through conduction (direct contact), convection (through a fluid such as air or water), or radiation (electromagnetic waves).
