This might be the description for thermal decomposition.
An insulator.
A material with a good thermal conductivity or a thermal conductor.
A material that transfers heat quickly is called a good conductor of heat. Examples include metals like copper and aluminum.
A insulator (a thermal insulator)
a thermal isolator
if ingenious rock is heated it becomes metamorphic rock.
The ability of a material to transfer heat is called thermal conductivity, while the ability to transfer an electric current is known as electrical conductivity.
Ductility refers to the ability of a material to be stretched without breaking. A ductile material can be drawn out into a wire or thread. Thermal conductivity refers to a material's ability to conduct heat. Materials with high thermal conductivity can quickly transfer heat.
A material that transfers heat slowly is called an insulator. Insulators have low thermal conductivity, which means they do not allow heat to pass through them easily. Examples of insulating materials include wood, plastic, and rubber.
The material that allows heat to pass through is called a conductor. Conductors have high thermal conductivity, which means they enable the flow of heat energy. Examples of conductors include metals like copper and aluminum.
A material that reduces the flow of heat is called an insulator. Insulators prevent the transfer of heat by reducing conduction, convection, and radiation. Common examples include fiberglass, foam, and certain types of plastic.
Materials that allow heat to pass through them easily are called conductors. Examples of conductors include metals like copper and aluminum.
