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 else can I help you with?
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 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 process of a primary way liquids and gas transmit by heat?
The process by which heat is transferred through liquids and gases is called convection. This occurs as heated particles become less dense and rise, transferring heat energy to surrounding particles. Cooler particles then become denser and sink, creating a circulating flow that transfers heat through the medium.
What is the ability to transmit electrical currents called?
The ability to transmit electrical currents is called conductivity. Materials that conduct electricity well are known as conductors, while those that do not conduct electricity are known as insulators.
Are heat and work path functions?
No, heat and work are not path functions. Heat and work are energy interactions between a system and its surroundings that depend on the process taken, not just the initial and final states. Path functions are properties whose values depend on the path followed to reach that state, such as change in temperature.
What does a infrared wave does?
Transmit heat.
What is the ability to transmit heat or ectrisity called?
The ability to transmit heat is called thermal conductivity, while the ability to transmit electricity is called electrical conductivity. These properties determine how efficiently heat or electricity can flow through a material.
In what form does radiant heat transmit?
Radiant heat transmits in the form of waves.
What is the ability or power to transmit heat electricity or sound?
I think the word you might be looking for is conductivity. Look up the definition and see if this word is what you are looking for.
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
The ability or power to transmit heat electricity or sound?
conductivity
What defines something able to transmit heat or electricity?
Conductivity.
What is something that does not transmit heat well called?
A non-conductor
Why are metals conductors of heat?
Because of their many valence electrons. The free-moving electrons transmit heat quickly.
Does heat transmit readily through a molecule?
No, heat does not transmit readily through a single molecule. Instead, heat is typically transferred through a material via the vibrations and movements of its atoms and molecules. These vibrations can be influenced by factors such as the material's thermal conductivity and specific heat capacity.
