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?)

The question is incomplete as it does not have the options which are:

•A. convection

•B. radiation

•C. conduction

•D. none of the above

Convection

Explanation:

The heat can be transferred from one state of matter to another state of matter through one of the three ways: the conduction, convection or radiation.

The convection is the way in which the heat is transferred when the molecules show bulk movement. As the air is heated, the air expands and the molecules move in bulk reaching the person as a result of which the person feels hot.

Thus, Convection is correct.

hello

i hope this

ya the other dude is right
