Example of situation with conduction, convection, and radiation

thermodynamics

I am studying heat transfer and have learned there are three kinds of heat transfer: conduction, convection, and radiation. Some examples are:

Conduction:

Touching a stove and being burned

Ice cooling down your hand

Boiling water by thrusting a red-hot piece of iron into it

Convection:

Hot air rising, cooling, and falling (convection currents)

An old-fashioned radiator (creates a convection cell in a room by emitting warm air at the top and drawing in cool air at the bottom).

Radiation:

Heat from the sun warming your face

Heat from a lightbulb

Heat from a fire

Heat from anything else which is warmer than its surroundings.

I have heard that for a vacuum flask all three types are important. Are there other examples where all three are important?
