Heat is transferred in one of three ways: conduction, convection, and radiation.
Conduction: molecules and atoms bang up against adjoining molecules and atoms and the higher energy (hotter) ones transfer some of their energy to the lower energy (colder) ones.
Convection: a mass of hot matter is physically moved to another region making the average energy of that region higher (once it is moved, it transfers energy to the rest of the surrounding material mostly via conduction). The movement can either be forced - like by a fan, pump, or mixing blade - or due to hotter material being less dense than colder material and thus rising due to buoyancy effects.
Radiation: Hotter material radiates in the electromagnetic spectrum. This radiated energy can be absorbed by any material it encounters, thus raising the average energy of the material, i.e. heating it. Hotter material radiates more; colder material radiates less. Because of the net difference in how much cold and hot materials radiate, there is a net transfer of energy from the hot material to the cold material.

What are the physical properties of metals non metals and noble gases?
metals conduct heat, transmit electricity, and are usually ductile. non-metals do not conduct heat well, do not transmit electricity and can't be hammered into shapes. noble gases cannot combine with any other elements.
What is the capacity to do work or produce heat?
Energy is the capacity to do work or to produce heat.
What is the advantage of the materials having low specific heat?
it means that water temperature stays the same which is good for any organisms living in it that is cold blooded because they cant control their body temperature internally and any heat fluctuation ,they would die.
What is the ability to transmit electrical currents called?
The ability of a material to transfer heat or electric current is called conductivity.
Capacity of a substance to do work?
heat
What does a infrared wave does?
Transmit heat.
What is the ability to transmit heat or energy?
Conductivity
In what form does radiant heat transmit?
Radiant heat transmits in the form of waves.
How does Earth's core transmit heat?
By conduction and convection.
What do conductors and insulators do?
Conductors transmit, while insulators don't. Usually, they transmit electricity and/or heat. Usually, they poorly transmit electricity and/or heat (insulators). Usually, the classification by electricity or by heat is highly corrected.
Why are metals good conductors oh heat?
the free-moving electrons transmit heat quickly
Elements that transmit energy and the heat easily are called?
soild
What defines something able to transmit heat or electricity?
Conductivity.
The ability or power to transmit heat electricity or sound?
conductivity
What is something that does not transmit heat well called?
A non-conductor
Does heat transmit readily through a molecule?
Yes, normally it does.
Elements that easily transmit electricity and heat display the property known as?
Elements that easily transmit (conduct) electricity and heat display characteristics of conductivity. They are called metals.
