Explain conductation
Answers
Answer:
why do our clothes get hot when we iron them? This is because heat is transferred from our hot iron to our clothes when they come in contact with each other. How is it that we have electricity in our homes? This is because the electric current travels through wires that conduct electricity. How is it possible to transfer heat between objects and for us to have electricity? This is all because of a very important process called conduction.
Conduction is the transfer of energy in the form of heat or electricity from one atom to another within an object by direct contact. Conduction occurs in solids, liquids, and gases. However, solids transfer energy most efficiently since the molecules in solids are most tightly packed, and the molecules are closer together, as shown in this figure. For liquids and gases, the density of the particles are generally lower than those of solids and the particles are farther apart, so the energy transfer is less efficient.
Solid, Liquid and Gas Particles
There are two main types of conduction:
Conduction of heat occurs when molecules increase in temperature; they vibrate, and this vibration and movement passes the heat energy to the surrounding molecules. Some examples of conduction of heat are accidentally touching a hot pot, or when a heating pad is applied to you directly and warms your muscles.
Explanation:
The flow of charged particles from one medium (transmission medium) to another is called electric conduction. An electric current is created by the flow of charges.The flow of charges is possible for two reasons Due to electric field When a voltage is installed between the two ends of a conductor (such as a metal wire), the electrons within the conductor start moving from the following potential to the higher potential. This process is called electric conduction.
