Materials such as wood, plastic, rubber, and glass are poor conductors of heat and do not transfer heat easily. These materials have low thermal conductivity due to their molecular structure, which makes them excellent insulators.
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 ability to transfer heat to another object is known as thermal conductivity. It describes how well a material can conduct heat energy through it. Materials with high thermal conductivity can transfer heat quickly, while materials with low thermal conductivity transfer heat slowly.
Thermal conductivity is the ability of an element to transfer heat. It quantifies how fast heat can be transferred through a material under a temperature gradient. Materials with high thermal conductivity can transfer heat quickly, while materials with low thermal conductivity transfer heat more slowly.
Insulator, same as for electricity. An example of insulators (of heat) is Styrofoam.
Heat transfer between materials that are touching is called conduction, where heat is transferred through direct contact. Heat transfer through empty space is called radiation, where heat is transferred through electromagnetic waves. Heat transfer by the movement of warm particles is called convection, where heat is transferred through the movement of liquid or gas.

Copper, aluminum, and graphite are three materials known for their ability to quickly transfer heat due to their high thermal conductivity properties. These materials are commonly used in applications where rapid heat transfer is necessary, such as in cookware, heat sinks, and electronic devices.
Insulators such as asbestos and styrofoam.
Materials transfer heat differently based on their thermal conductivity, which is a measure of how well a material conducts heat. Materials with high thermal conductivity, like metals, transfer heat more readily than materials with low thermal conductivity, such as insulators. This difference is due to the ability of the material's atoms or molecules to vibrate and transfer heat energy.
The three methods of heat transfer are conduction (transfer of heat within a material or between materials in direct contact), convection (transfer of heat through fluid movement), and radiation (transfer of heat through electromagnetic waves).
