# Conduction examples (driving)

The term driving (Conduction) has two definitions depending on the context . There is vehicle driving and electric driving.

### Conduction (vehicles)

It is about the ability to steer a car, a motorcycle and any other means of transportation. It is not just about starting the vehicle , but about understanding the traffic rules and corresponding laws .

To drive, in any country, you must be authorized to do so. It is usually achieved with a license, which is a certificate of having passed a driving test. In each country, perhaps some extra document will be required.

On the other hand, the vehicles as such also need to be adjusted to the norm: have a registered license plate, insurance (in some countries), that their lights work, etc.

### Driving or handling examples

• Driving a car correctly, that is, they are skipping a traffic rule and without affecting the environment.
• Drive a motorcycle of any type: scooter, high-displacement, electric, racing, etc.
• To ride a bicycle.
• Although it has another name, to direct an airplane, a ship or a train, essentially it is also a form of driving.

### Conduction of heat or electricity

Conduction of electricity refers to the circulation of heat by electrically charged particles through a conductor.

The goal of thermal conduction is to heat an object that is cold. Its formula is expressed in the form:

Where T: temperature; x: direction of heat flow.

The heat transmitted by conduction per unit time qk is proportional to the temperature gradient dT / dx multiplied by the area A, through which it is transferred.

On the other hand, the heat flow will depend on the thermal conductivity k, the physical property of the medium to transfer energy [W / m K]. For this, the Fourier Heat Conduction Law is applied .

Driving examples

• Along instruments for handling coal or other potentially very hot objects. If its length were shorter, the heat transfer would be faster and neither end could be touched.
• The heat that the hair receives from the iron.
• Ice on a hot surface melts through heat conduction.
• When trying to heat a liquid, the fire heats the container and after a few minutes the liquid will also heat up.
• The spoon that heats up when inserted into a hot cup of coffee.
• The plates that heat textiles to eliminate “wrinkles”.
