Conduction
* Most conduction carries heat.
* Some conduction has vibration.
* Some conduction occurs at atomic levels
  - in channels
* allows heat to spread from one solid object to another as long as the parts are touching.
* describes the flow of energy through a material rather than the flow of the material.
* fields Current and potential in a resistive medium.
* involves heat transfer from one object to another by actual contact
  - solid objects touching each other
* is about the transfer of energy by collisions between one particle and another
  - also a common way of transferring heat through gases
* is an important heat-transfer mechanism in Earth's crust and lithosphere
  - way that heat travels in space, but only within a spacecraft
* is another way that heat moves
  - objects can become charged
  - based upon the principal that heat flows from warm to cold
  - by electrons and holes
  - caused by molecular motion in a solid
  - greater in solids, where molecules are in constant contact
* is heat energy traveling through a solid
  - moving from one object to another through contact
* is heat transfer through a material or from one material to another in direct contact
  - solid material, such as a brick wall
  - most effective in solids and liquids, less important in gases
  - much more efficient than convection in transferring heat
* is one of the most common ways to transfer heat
  - three methods of transferring energy, including convection and radiation
  - responsible for an iron frying pan's handle getting too hot to touch
  - restricted to solids
* is the flow of heat energy through solid bodies
  - main process for transporting heat through the lithosphere
  - movement of heat from particle to particle
* is the movement of heat through a solid material
  - a substance by the collision of molecules
  - passing of heat through a medium
  - primary mode of heat transfer in soil
* is the process of heat transfer by direct contact with another surface
  - losing heat through physical contact with another object or body
  - result of collisions between the particles making up the material
  - transfer and distribution of heat energy from atom to atom within a substance
* is the transfer of heat between objects whose surfaces are in contact with each other
  - by intermolecular collisions
  - energy from one substance to another or within a substance
  - from two objects that contact each other
  - within a material due to intimate contact between molecules
* is the transfer of the heat by atomic or molecular collision
  - through a solid object, liquid or gas
  - transport of heat through solids by direct contact
* is the way heat moves through materials, traveling from molecule to molecule
  - travels through an object
  - very rapid if the temperature difference is large
  - when a warmer object touches a cooler one
* means heat or electricity traveling through something
  - that heat can be transferred between two objects that are touching
* more effective way to transfer heat than convection.
* moves heat from hot to cold.
* occurs between two materials in direct contact
  - either by the movement of electrons or the movement of ionic atoms or molecules
  - from molecular collisions when there temperature difference
* occurs in liquids, solids and gases
  - solids, liquids, or gases that are at rest
  - mostly in solids
  - when energy is passed directly from one item to another
* occurs when heat energy moves from molecule to molecule through a substance
  - flows from warm materials to colder materials
  - is transferred directly through a medium
  - something hot touches something less hot
  - the electrons are excited by heat energy and start to move faster
* occurs when two object at different temperatures are in contact with each other
  - substances at different temperatures are in contact
* only occurs when an electron is excited across the bandgap into the conduction band.
* physical phenomenon
* relies on direct contact of one hot surface to heat another.
* requires a solid material and a temperature difference across it
  - objects to be in contact with one another
* takes place most readliy in solids, but also takes place in liquids and gases
* then occurs as an electron is present within the voltage.
+ Heart, Heart's Pacemaker: Anatomy of the cardiovascular system
  * After the electrical impulse goes through the AV Node, the electrical impulse will go through the 'conduction system' of the ventricle. Conduction means heat or electricity traveling through something. This brings the electrical impulse to the ventricles. Bundle means strings or wires grouped together in parallel. The left bundle branch travels to the left ventricle and the right bundle branch travels to the right ventricle. At the end of the bundle branches, the electrical impulse goes into the ventricular muscle through the Purkinje Fibers. This is what makes ventricle contraction take place and makes ventricular systole.
