The driving it is one of the three processes through which heat is transferred from a body with a higher temperature to a body with a lower temperature. This process refers to the transmission of heat energy through the body's molecules, which can be present in a solid, liquid or gaseous state..
In conduction there is no real displacement of the heat energy particles, but rather these are agitated and spread through the body. Conduction transfer is invisible: a metal tool heats up when it comes into contact with fire with no changes in the tool.
Conduction is a transfer of heat that occurs from a body with a higher temperature to a body with a lower temperature.
When the ice melts, it's all about driving. If we warm our hands by holding a cup of coffee, it is also driving. When we iron clothes, heat conduction intervenes. Even when we get burned by a flame, it happens due to conductive heat transfer.
This shows that in our day to day, there are hundreds of examples of heat transfer through conduction. Here are more examples of this process.
Hot liquids transfer heat to the container that contains them, causing the container to heat up a bit.
For example, if hot coffee is poured into a cup, it will become hot.
When it's cold, people drink hot drinks to keep warm. Holding the beverage container long enough will cause the hand of the person holding it to get a little warmer..
The sediments on the beach absorb the heat of the sun and this heat is transferred to our feet if we walk barefoot on the sand.
Compresses (hot water bottles) are used to relax the muscles. Heat is transferred from the compress to the skin and from there to the muscles.
When a barbecue is made, the instruments used to turn the meats are made of metal. When these tongs come into contact with the broilers, the heat transfer begins.
If the tweezers remain in contact with the heat source for a long time, the skin of the person holding them could be injured..
Radiators are responsible for producing heat to heat houses. For this reason, the surface of these appliances is usually hot. Placing your hand on the radiator will transfer the heat and we may even feel pain if the heat is excessive..
If an ice cube is placed on a person's hand, heat will transfer from the skin to the cube, causing the cube to melt..
When the engine of a car is started, the hood becomes hot due to the transfer of heat generated by the operation of the engine.
The irons are heated to eliminate wrinkles in clothing. When the iron comes into contact with the fabric, the heat begins to transfer.
The pokers that are used to move the pieces of wood in the fireplace are made of metal, which are good conductors of heat. If a poker is left in contact with the heat source in the fireplace, the heat will be transferred from it to the poker.
If the poker remains in contact with the fire long enough, the heat will be conducted to the full extent of the metal tool..
Coins tend to be cold, or at least colder than human skin. If a coin is held in the hand, heat will transfer from the skin to the coin, causing it to heat up..
On a cold day, people can hug each other to keep each other warm. Heat is transferred from the highest temperature individual to the lowest temperature individual.
Hot food conducts heat to the plate it is on (if it is made of a conductive material, such as ceramic).
If we hold a piece of chocolate for a long time, it will melt because of the heat that is being transferred from the hand to it..
If, with our skin uncovered, we touch a flame (from a candle, from the kitchen, among others), the heat will be transferred from the fire to our skin, causing us to burn.
The stones absorb the heat of the sun. If we touch one that has been exposed to the sun for a long time, the heat will transfer from it to our skin.
Traditional light bulbs get hot when they are on. If we touch one on, the heat will transfer from the bulb to our skin, producing burning.
When ice is added to a beverage, heat is transferred by conduction from the beverage to the ice causing the ice to thaw..
If a teaspoon is left in a bowl of hot soup, the heat is transferred from the liquid to the metal.
When we boil water, the heat is conducted from the flame to the pot that contains the water. From there, the heat is transferred to the water causing it to reach its boiling point..
