Answer:
conduction: the process by which heat or electricity
is directly transmitted through the material of à substance when there is a difference of température or of electrical potential between adjoining regions, without movement of the material is called conduction.
convection: the movement caused within a fluid by the tendency of hotter and therefore less dense material to raise, and colder denser material to sink under the influence of gravity, which consequently results in transfer of heat.
radiation: radiation means the energy that comes from a source and travels through space at the speed of light.
insulators: insulators are the material that keeps secured from the energies like electricity, heat or cold for easily transferring of the energy, such as in wire.
reflectors: a piece of glass or metal for reflecting light in the required direction is known as reflector.
