"Conduct" and "convection" are two different processes of heat transfer.
When heat is transferred through a gas, the primary mechanism is convection.
by convection
All substances, including oxygen, conduct heat. Oxygen, though, is a poor conductor of heat. Since it is a gas at room temperature it will transfer heat primarily by convection.
Convection is the transfer of heat by circulation through a gas or liquid.
It conducts by heat by a soruce.
Convection is the transfer of heat through the movement of a fluid, whether liquid or gas.
No, a vacuum does not conduct heat as it does not have any particles to transfer thermal energy. Heat transfer can only occur through conduction, convection, or radiation, and a vacuum eliminates the possibility of conduction and convection.
In convection, heat transfer occurs through the movement of fluid particles, such as air in this case. As the gas flame heats the air surrounding the potatoes, the hot air rises and carries the heat towards the potatoes. The skewer helps to conduct the heat from the air to the inner layers of the potatoes, cooking them evenly.

Hydrogen is a poor conductor of heat compared to other elements because it has low thermal conductivity. In its molecular form (H2), hydrogen mainly transfers heat through convection rather than conduction due to its low density and lack of free electrons for effective thermal energy transfer.
