Answer 1

Answer:

❤️❤️Heating is very beneficial in our day to day lives. the process can be used for many things like:

Cooking

Micro-waving something

Using this process in heaters which warm you up

To melt and cut Thermoplastics easily for some projects

Roasting

Boiling

Baking

Make furniture for those interested in carpentry❤️❤️

Explanation:

❤️❤️hello dear here is your answer mark it brainlist ok and follow me... :) ☺️☺️❤️❤️

Answer 2

Based on its medium, the heat transfer process consists of three types and conduction is one of them. Conduction is the transfer of heat through an intermediate medium of substances, but only the energy of it without accompanied by the media transfer.

The heat flow speed is affected by the temperature difference between the delivery ends (ΔT), the area of the conducting cross section (A), the tip spacing having the temperature difference (L), and the type of conductor.Mathematically can be written with the following formula:H = Q / t = k. A. ΔT / L

FEW EXAMPLES IN DAY TO DAY LIFE ARE -

• The heat from a hot coffee makes the cup itself hot  A metal spoon becomes hot from the boiling water inside the cup

• You decide to touch the handle of the skillet after it has been on for several minutes, and now the handle is hot, too. This is because heat was conducted through the portion of the skillet in contact with the stovetop all throughout the rest of the skillet.

• A shirt is placed on an ironing board to be ironed. Heat from the iron is conducted to the shirt, making it easy to iron out all those unsightly wrinkles and make the shirt look sharp.

• The engine of a car is turned on, and the hood becomes warm due to the conduction of heat from the engine to the hood of the car.

• A cube of ice is placed into the hand of a man. Over time, heat conducted from the man’s hand to the ice cube will cause the ice to melt.

• A boy grabs a penny from his tabletop, and it feels very cold to the touch. After holding it for a few seconds, the heat from his hand is conducted to the metal coin.

• A boy places a hot dog onto the end of an unraveled metal clothes hanger and begins to cook it over the fire. After a time, the hanger begins to feel hot due to the heat conducted from the hot fire all along the piece of wire.

• When a piece of hot lasagna is placed onto a porcelain plate, the plate will feel warm to the touch after several minutes due to the conduction of heat from the just-cooked food to the plate on which it sits.

• An individual builds a fire, and then moves around the burning logs with a poker. Heat is conducted from the burning logs to the poker, making the end of the poker become red-hot if it is left in the fire too long.

• Boiling water - The heat passes from the burner into the pot, heating the water at the bottom. Then, this hot water rises and cooler water moves down to replace it, causing a circular motion.

• Hot air balloon - A heater inside the balloon heats the air and so the air moves upward. This causes the balloon to rise because the hot air gets trapped inside. When the pilot want to descend, he releases some of the hot air and cool air takes it place, causing the balloon to lower.

• When a young girl walks outside barefoot on a hot summer day, the heat from the asphalt is conducted to her feet, and her feet become hot. This is because heat is conducted from the asphalt to the girl.

• A young boy comes inside after playing on a snowy day, and huddles up to his mother to become warm. This is because heat is transferred from his mother’s body to his own through the process of conduction.

These examples of heat conduction are designed to give you a better idea of just how this process works. The next time you are cold, you can put the practice of heat conduction to work for yourself.
