When roasting a marshmallow the transfer of heat from the flame to the marshmallow is radiation.Radiation is the transfer of heat through energy waves. It can actually be considered conduction as well if you place the marshmallow into the flame, since that is the direct transfer of heat.
Roasting marshmallows over a campfire is an example of radiant heat. The heat is transferred from the fire to the marshmallow through electromagnetic waves.
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.
Convection, and radiation with a small amount of conduction cooks the marshmallow. The primary heat transfer is convection from the hot gasses passing over the marshmallow.
becuase u made it angry by roasting his cousin
A marshmallow cooks through conduction, where heat is transferred from the hot surface of the fire to the marshmallow as they are in direct contact. Additionally, some radiation from the fire contributes to the cooking process as well.
Yes, anything that burns (combust) is a chemical change
That would be a chemical change.
When roasting a marshmallow over a fire, chemical energy stored in the marshmallow is converted to thermal energy as the marshmallow heats up and starts to melt and brown. This is an example of energy transformation from chemical energy to thermal energy.
Roasting a marshmallow is a physical change, not a chemical change. The marshmallow undergoes a change in its physical state as it is heated, but its chemical composition remains the same.
It depends on how long you roast it! If you simply allow it to warm up, it is still a marshmallow after roasting, so it is a physical change. If you like it crispy and burnt, it is a chemical change because it starts off white and then it eventually melts and turns brown. This browning is oxidation, a chemical process where some of the marshmallow's sugar is burnt and carbon dioxide is released into the air.
