Suppose you are standing a few feet away from a bonfire on a cold fall evening. your face begins to feel hot. what is the mechanism that transfers heat from the fire to your face? (hint: is the air between you and the fire hotter or cooler than your face? )

•a. convection
•b. radiation
•c. conduction
•d. none of the above

diagram is missing, but i will try to explain your doubt.
