Question

In 1792, Benjamin Franklin designed a wood burning stove to heat rooms. The front of the stove was open, allowing heat to spread into the room. The back of the stove was closed, but had an air intake that increased air circulation. Fires lit in traditional fireplaces received less oxygen than those lit in Franklin stoves. If a ceramic cup is placed on top of a lit Franklin stove, it will gradually HEAT UP. What is the mode of heat transfer from the stove to the ceramic cup?

Answer 1

Conduction.

Step-by-step explanation:

The mode of heat transfer from the Franklin stove to the ceramic cup on top of it is primarily conduction.

Conduction is the transfer of heat through direct contact between two objects with different temperatures. In this case, the ceramic cup is in direct contact with the hot surface of the Franklin stove, and heat is transferred from the stove to the cup through the physical contact of the materials. The heat from the stove is conducted through the materials of the cup, causing it to gradually heat up. While convection and radiation may also play a role in heating the surrounding air and objects in the room, the initial transfer of heat from the stove to the cup occurs through conduction due to the direct contact between them.
