A marshmallow over a bonfire is a radiant heat transfer. The marshmallows are not in direct contact with the flame but are held very close to reduce burning.
Toasting marshmallows is an example of heat transfer through convection. The heat from the fire warms the air, which then rises and carries the heat to the marshmallow, cooking it evenly.
You feel the warm glow of a bonfire through the process of heat transfer known as radiation. The heat energy from the fire is emitted in the form of electromagnetic waves, which travel through the air and reach your skin, making you feel warm.
A bonfire produces mainly thermal energy in the form of heat and light. The burning of the wood releases stored chemical energy in the form of heat and light energy.
The three types of heat transfer are conduction, convection, and radiation. Conduction is the transfer of heat through direct contact of particles. Convection is the transfer of heat through the movement of fluids or gases. Radiation is the transfer of heat through electromagnetic waves.
Conduction, which is the transfer of heat through direct contact between particles, cannot take place in a vacuum because there are no particles present to transfer the heat.

When your hand is on a heat pad, heat transfer is occurring through conduction. This is because the heat from the pad is being directly transferred to your hand through physical contact.
The heat transfer process exemplified by heat traveling through a pan to warm food is known as conduction.
