Consider the following familiar situations where some heat transfer takes place. 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.

• 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
