It is heat transfer at speed higher than 0.3 Mach.
Materials with high thermal conductivity, such as metals like copper and aluminum, are able to speed up the transfer of heat energy. These materials are efficient at conducting heat and allowing it to flow through them quickly. Additionally, materials with good heat conduction properties, such as graphite and diamond, are also effective at speeding up the transfer of heat energy.

Materials with low thermal conductivity, such as wood, rubber, and some plastics, do not let heat flow through easily. These materials have a high resistance to heat transfer, making them good insulators.
Iron is a good conductor of heat, which means it can facilitate the flow of heat. When heated, iron can quickly transfer heat energy from one part of an object to another due to its high thermal conductivity. This property makes iron useful in applications where efficient heat transfer is required, such as in cooking utensils or industrial equipment.
Convection primarily occurs in fluids (liquids and gases) because of their ability to flow and carry heat through movement. In solids, heat transfer mainly occurs through conduction due to the fixed position of atoms and lack of fluid movement. However, in certain solids with high thermal conductivity, such as metals, heat transfer can also occur through convective heat transfer at high temperatures or in specific conditions.
Materials with low thermal conductivity are better heat insulators, such as fiberglass, foam, or aerogel. These materials trap air or have high resistance to heat flow, hence reducing heat transfer.
Yes, heat moves from areas of high temperature to areas of low temperature in a process known as heat transfer. This is a fundamental principle in thermodynamics that drives the flow of energy in the form of heat.

Good conductors of heat typically have high thermal conductivity, which allows heat to transfer through the material quickly and efficiently. These materials often have a high density and a solid structure that allows heat to flow easily. Metals like copper, aluminum, and silver are prime examples of good conductors of heat.
Foam is a poor conductor of heat due to the presence of trapped air pockets within its structure. These air pockets create thermal resistance to heat flow, slowing down the transfer of heat through the material. Additionally, the high surface area-to-volume ratio of foam further hinders heat transfer by reducing the contact points for heat conduction.
Materials that do not transfer heat easily are called insulators. Common examples include wood, plastic, rubber, and glass. These materials have high resistance to heat flow due to their molecular structure, making them effective at maintaining temperature differences.
Yes, a conductor of heat tends to cool quickly because it allows heat to flow rapidly from the object to its surroundings. Conductors like metals have high thermal conductivity, which means they can transfer heat efficiently.
