Question

Write any four practical applications of transfer of heat by conduction . ​

Answer 1

Explanation:

Conduction Of heat transfer is the transfer of internal energy by microscopic collisions of the particles and the movement of free electrons within a body. Colliding particles, which contain molecules, atoms, and electrons, transfer kinetic energy and P.E, together called internal energy. Conduction of heat takes place in all phases of matter: solid, liquid, and gas.

The rate at which energy is conducted as the heat between two bodies depends on the temperature difference between the two bodies which are in contact with each other.

The heat automatically flows from a hotter body to a colder body. For example, heat flows from the hot plate of a stove to the bottom of a sauce pan in contact with it.

Heat will transfer from a hot burner on the stove into a pot or pan. A metal spoon becomes hot from the boiling water inside the pot. Chocolate candy in your hand will eventually melt as heat is conducted from your hand to the chocolate. When ironing a skirt, the iron is hot and the heat is transferred to the skirt.

Answer 2

Question :

Write any four practical applications of transfer of heat by conduction . ​

Answer :

Any four practical applications of transfer of heat by conduction are as follows :

• Utensils used to handle charcoal or other very hot substances. Keep in mind that the extension is long so that the heat transfer is slower.

• HUMAN BODY : We can warm our back muscles with a heating pad. As the pad heats up, it transfers heat to the part of your body that it is in contact with. This is a process of heat transfer by conduction .
• COOKING : The handles of the cooking utensils are made of materials like plastic and sometimes wood which cannot conduct heat when carried by the cook;
• During winter , we wear woolen clothes since wool is a bad conductor of heat and it doesn't allow the heat from the body to get conducted outside.
