Toasting marshmallows is an example of heat transfer through convection. The heat from the fire warms the air, which then rises and carries the heat to the marshmallow, cooking it evenly.
The heat transfer involved when a marshmallow is roasted over a bonfire is primarily conduction. The heat from the flames directly heats the marshmallow through direct contact, causing it to melt and become gooey.
A marshmallow cooks through conduction, where heat is transferred from the hot surface of the fire to the marshmallow as they are in direct contact. Additionally, some radiation from the fire contributes to the cooking process as well.
Heat transfer in the fire service refers to the movement of heat energy from a heat source to cooler objects or areas by means of conduction, convection, or radiation. Understanding heat transfer is crucial for firefighters to anticipate fire behavior, assess potential hazards, and effectively control fire spread.
Heat transfer from the fire to the boat can occur through conduction if the boat is in direct contact with the fire or through radiation if the heat is emitted in the form of electromagnetic waves that reach the boat. Heat may also transfer through convection if the hot air or gases from the fire come into contact with the boat's surface and heat it up.
Toasting marshmallows is an example of heat transfer through convection. The heat from the fire warms the air, which then rises and carries the heat to the marshmallow, cooking it evenly.
Convection, and radiation with a small amount of conduction cooks the marshmallow. The primary heat transfer is convection from the hot gasses passing over the marshmallow.
When roasting a marshmallow the transfer of heat from the flame to the marshmallow is radiation.Radiation is the transfer of heat through energy waves. It can actually be considered conduction as well if you place the marshmallow into the flame, since that is the direct transfer of heat.

Heat transfer from the fire to the boat can occur through conduction if the boat is in direct contact with the fire or through radiation if the heat is emitted in the form of electromagnetic waves that reach the boat. Heat may also transfer through convection if the hot air or gases from the fire come into contact with the boat's surface and heat it up.
Broiling is a form of heat transfer called radiation, where heat is transferred through electromagnetic waves directly to the surface of the food being cooked.
During the early stages of a fire, the major mode of heat transfer is typically convection. As the air is heated by the fire, it becomes less dense and rises, carrying heat energy away from the fire and transferring it to cooler surfaces. Conduction and radiation also play a role in heat transfer during a fire.
The type of heat transfer in this scenario is radiation. The heat from the fire is emitted in the form of electromagnetic waves, which transfer energy to the bread without the need for direct contact.
