Consider the following situations where heat transfer takes place.

• Your feet get cold standing outside in the winter
• Your egg cooks in a pot of water on the stove (before it boils ... after it boils ... in a microwave)
• The northern hemisphere gets cold in the winter
• Your thermos of coffee gets cold
• The inside of your house gets hot on a summer day

Identify whether:

conduction (heat exchange through physical contact, like an ice pack on your forehead),
convection (bulk transport of fluid like when hot air from your fireplace makes it to the ceiling), or
radiation (transport of energy by electromagnetic waves),

or possibly some combination, is responsible for the energy transport.

A. Conduction
B. Convection
C. Radiation
D. Conduction and Convection
E. Conduction and Radiation
F. Convection and Radiation

You've probably heard "you lose 60% of your body heat through your head, so wear a hat when it's cold outside!" What do you think of this statement?
