Spontaneous combustion is a natural heat-producing process that can lead to a fire. It occurs when materials self-heat to the point of ignition without an external heat source. This can happen with certain materials like oily rags, coal, or hay when they are stored improperly.
Heat transfer occurs through the flow of materials. When materials with different temperatures come into contact, heat will transfer from the hotter material to the cooler one until they reach thermal equilibrium. This can happen through conduction, convection, or radiation.
Materials that conduct heat well, such as metals like copper and aluminum, transfer heat the best. These materials have a high thermal conductivity, allowing them to efficiently transfer heat from one point to another. Insulating materials, on the other hand, do not transfer heat well and are used to reduce heat transfer.
The specific heat of a material determines how much heat energy is needed to change its temperature. Materials with high specific heat require more energy to heat up or cool down compared to materials with low specific heat. This means materials with high specific heat will heat and cool more slowly than those with low specific heat.
Materials that are good conductors of heat include metals such as copper, aluminum, and iron. Other materials like silver and gold are also excellent conductors of heat. These materials allow heat to pass through them easily due to the movement of free electrons within their atomic structure.

Materials that are poor conductors of heat are Plastic and Wood "example."
Some, but not all. Some materials are insulators- heat does not travel well through them.

Thermal conduction happens fastest in materials with high thermal conductivity, such as metals like copper or aluminum. These materials have closely packed atoms and free electrons that allow heat to move quickly through them. Additionally, thermal conduction is most efficient in materials with good thermal contact and large surface areas for heat transfer.
Materials with high thermal conductivity, such as metals like copper and aluminum, are better for transferring heat. These materials are able to quickly and efficiently conduct heat from one area to another. Insulating materials, on the other hand, are better at preventing heat transfer.
