What are 3 examples of conduction?

Answer 1

• Metals are the most obvious example. Electrical conductivity in a copper wire is the result of electrons flowing along an electrical conductor as is the case with DC, with AC the electrons oscillate back and forth and hence have a period that can be modelled using trigonometry.

• Ionic solutions can conduct electricity. This involves solutions of ions that can carry a current between two potentials by virtue of being charged. This is how sodium chloride dissolved in water will increase its conductivity.

• Ionic liquids can conduct electricity, much in the same way as ionic solutions. The difference lies in the fact that these ions are not dissolved in a solvent but exist as chsrged ions in the liquid state.

• Solid state ionic conductorst can conduct by mechanisms that involve ions passing through channels in the solids crystal lattice.

• A Plasma Gas can conduct electricity as their electrons are delocalised from their atomic orbitals and consequently can move independently of the nucleus.

• Some minerals such as the Perovskite class can conduct electricity, most famously the cuperate high temperature super conductors are perovskite minerals.

• Semimetals such as graphite will conduct, electrons delocalised into the unhybridized P orbitals are responsible.

• Semiconductors and compound semiconductors can conduct electricity. An example would be Gallium Arsenide

• Certain nanomaterials conduct electricity such as certain types of carbon nanotubes.

add. But conductivity can also refer to sound and vibration waves, and to thermal energy.

Answer 2

A radiator in a car:

the antifreeze/coolant carries heat from the cylinder walls to the radiator which has metal fins with a lot of surface area that air flows over. The path is - cylinder walls, coolant, radiator fins, air passing by.

Metal pot for cooking:

the pot receives the heat or flame and conducts it not only up the middle of the fluid - but up the walls of the pot increasing the radiant are.

Closed circuit steam engine:

Water is warmed in a metal container, the heated water flows to a nozzle under pressure & becomes steam that turns a turbine, then goes to a heat exchanger (a radiator) and returns as cool liquid to start again.

Answer 3

1. Boiling water. 2. Shaking hands. 3. Burning your hand on a stove.

Answer 4

an thermal Conduction- touching a burning stove and getting burned, another one is letting ice e melt our hand.

Answer 5

Rubbing your hands together
