Yes, heating a pot over a stove is an example of conduction. As the stove heats the bottom of the pot, the heat is transferred through the pot's material. Roasting marshmallows over a campfire would also be an example of conduction, as the heat from the fire is transferred directly to the marshmallows.

When you put marshmallows in a fire, it is often referred to as "toasting" or "roasting" marshmallows. This popular activity typically takes place during camping trips or outdoor gatherings, where people skewer marshmallows on sticks and hold them over an open flame until they become golden brown and gooey. Roasted marshmallows are commonly used to make s'mores, a sweet treat that combines them with chocolate and graham crackers.
