Opening an oven door warms the air around the oven. What type of heat transfer is occurring in this situation?
A. Conduction
B. Convection
C. Disproportionation
D. Radiation
A
The heat transfer occurs when excited air molecules from the oven excite air molecules outside the oven. These particles then excite other particles, transferring the heat by conduction. Conduction occurs when the heated particles actually travel; radiation occurs when the heat is transferred through black body radiation.
