Convection - hot air raises -- smoke and other hot air goes up.
Conduction - anything in contact with the fire - a pot, a Poker, etc conducts the heat
Radiation - some of the energy ( heat) is released as infrared (heat) waves
you can feel the heat without touching the fire thru radiation of these i-r waves.
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.
The heat waves rising from the asphalt demonstrate convection, which is the transfer of heat through a fluid (in this case, the air) due to density differences caused by temperature variations.
The three forms of heat transfer are conduction, convection, and radiation. Conduction is the transfer of heat through direct contact of particles, convection is the transfer of heat through the movement of fluids or gases, and radiation is the transfer of heat through electromagnetic waves.
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.

When a marshmallow is cooked over a fire, it uses the heat transfer method of conduction. The heat from the fire is directly transferred to the marshmallow through direct contact, causing it to melt and cook.
The three forms of heat transfer are conduction, convection, and radiation. Conduction is the transfer of heat through a material without any movement of the material itself. Convection is the transfer of heat through the movement of fluids or gases. Radiation is the transfer of heat through electromagnetic waves.
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.
The heat you feel when you put your hands above a fire is primarily due to radiant heat transfer. This is the transfer of heat through electromagnetic waves emitted by the fire that heats up your skin. Additionally, convection currents created by the rising hot air from the fire also contribute to the heat you feel.
In a structure fire, convection is the most important method of heat transfer. Convection is the transfer of heat through the movement of fluids like air or gases. In a structure fire, hot air and gases rise, carrying heat with them and spreading the fire to other parts of the structure.
The energy transfer of a fire involves conversion of chemical energy stored in fuel to heat and light energy through combustion. The heat and light are emitted as the fire burns, providing warmth and illumination to its surroundings.
