Why does the pot handle become hot when it is put on stove?

The pot handle becomes hot when put on the stove because of heat transfer. Here's how it works:

1. Heat Source: The stovetop provides heat energy.

2. Conduction: This heat energy is transferred from the stovetop to the bottom of the pot. Metals, like the pot, are good conductors of heat, meaning they easily transfer heat through them.

3. Conduction through the Pot: The heat energy continues to travel through the pot, including its handle.

4. Temperature Rise: As the heat energy flows through the handle, it raises the temperature of the handle's material.

5. Hot Handle: Eventually, the handle becomes hot enough to be uncomfortable to touch.

Why are some handles not hot?

* Insulation: Some pot handles are insulated with materials like silicone or wood, which are poor conductors of heat. This prevents the heat from reaching your hand.

* Heat-Resistant Materials: Some pot handles are made of materials that resist heat transfer, such as Bakelite.

Important Safety Note: Always use oven mitts or pot holders when handling hot pots and pans, even if the handle appears to be cool to the touch. The handle may still be hot enough to cause burns.
