The process where heat transfers from one object to another through empty space, allowing fire to spread from one building to another, is called radiation. Radiation is the transfer of heat via electromagnetic waves and does not require any medium (such as air or solid material) to travel through, which means it can occur across empty space. This is how heat from a fire can radiate through windows or open spaces and ignite materials in adjacent buildings, causing fire to spread rapidly between structures
. In summary:
- Radiation transfers heat through electromagnetic waves across empty space.
- It enables fire to spread from one building to another without direct contact or a physical medium.
- This is a common and hazardous way that fires propagate between buildings
