Fires can spread by means of:
conduction, convection and radiation.
No, a stable atmosphere typically suppresses fire behavior by limiting vertical movement of air and reducing convection. Stable conditions can hinder the development of strong updrafts and spread of fire.
A fire uses convection by heating the surrounding air, which becomes less dense and rises. As the hot air ascends, it creates a convection current, pulling in cooler air from the surroundings to replace it. This process not only helps to spread the heat from the fire but also facilitates the combustion process by supplying fresh oxygen to the flames. Ultimately, convection enhances the efficiency and intensity of the fire.
You are correct because the heat of the fire causes the hot air to rise quickly by convection currents and the intense radiated heat ignites materials like fabrics, plastics and light wooden objects like chairs.
Three paths of fire spread in a residential structure are through conduction (heat transfer through materials), radiation (heat transfer through electromagnetic waves), and convection (heat transfer through air movement). These paths can lead to rapid fire growth and spread within a building.
A fire is radiation.
Using flour to put out a grease fire is not recommended as it can cause the fire to spread. It is safer to smother the fire by covering it with a metal lid or baking soda, or by using a fire extinguisher designed for grease fires.

convection
Campfires transfer heat primarily through convection and radiation. Convection occurs as the hot air rises from the fire, creating air currents that spread the heat. Radiation involves the emission of electromagnetic waves, which heat objects or surfaces that are in the fire's line of sight.
