Answer:
The transfer of thermal energy through conduction occurs when heat is transferred between objects that are in direct contact with each other. In the context of sitting around a campfire and roasting marshmallows, there are a few examples of conduction.
Explanation:
One example is when you hold a marshmallow on a stick over the campfire. The heat from the fire is conducted through the stick and then to the marshmallow, causing it to heat up and eventually melt. This transfer of thermal energy through the stick is an example of conduction.
Another example is when you hold a marshmallow in your hand after it has been roasted. The heat from the marshmallow is conducted through your hand, warming it up. This transfer of thermal energy from the marshmallow to your hand is also an example of conduction.
In both of these examples, the transfer of thermal energy occurs through direct contact between objects. The heat moves from the hotter object (the fire or the marshmallow) to the cooler object (the stick or your hand) until thermal equilibrium is reached.
Overall, conduction plays a role in the transfer of thermal energy when sitting around a campfire and roasting marshmallows. It helps to understand how heat is transferred between objects and how it affects the temperature of the objects involved.
