Examples of Heat Transfer by Conduction

Heat transfer by conduction occurs when heat energy is transferred through a substance without the substance itself moving. This process occurs in solids, where the atoms and molecules are closely packed and can transfer energy through collisions. Here are some examples of heat transfer by conduction:

1. Cooking Utensils: - When a metal spoon is placed in a hot liquid, the handle of the spoon becomes hot due to conduction. The heat from the liquid is transferred to the handle of the spoon through conduction.

2. Heating a Metal Rod: - When one end of a metal rod is heated, the heat is conducted along the length of the rod, gradually heating the entire rod. This is an example of heat transfer by conduction in solids.

3. Touching a Hot Pan: - When a person touches a hot metal pan, heat is transferred from the pan to the person's hand through conduction. The metal of the pan conducts heat to the person's skin upon contact.

These examples illustrate how heat transfer by conduction occurs in everyday situations, where heat energy is transferred through direct contact within a substance.
