Radiant heat transfer is the primary way you feel heat from a campfire. There would also be convective and conductive heat transfer to the air.
Heat Energy
Conduction
water would heat up
If you are asking about a box filled with a gas, then heat transfer can modeled as conduction through a solid. The requirement would have to be no fluid flow (obviously there is movement at the micro level), and the conductive heat transfer coefficient would be very low.Convection heat transfer is dependent on that conductive heat transfer coefficient of the liquid and is based on something called the Nusselt number.If you are asking about heat transfer through a completely void space, then heat would travel by means of radiation.

Heat Energy
A campfire uses all three heat transfer methods conduction, convection, and radiation.
HEAt energy
Radiation
Conduction
A campfire is an example of radiation because heat is being emitted from the fire. The heat is what is being radiated, and the heat is a characteristic of the campfire.

Convection heat transfer is the transfer of heat by the movement of a fluid.
From the fire the transfer is by radiation. From the coffee cup to Megan's hands the transfer is by conduction
