Chapter 2: Thermal physics — Part 9

01 Everyday applications

Apply conduction, convection and radiation to simple situations such as:

• Heating objects such as kitchen pans — a metal pan conducts from the hob into the food; a plastic handle insulates.
• Heating a room by convection — warm air rises from a heater and circulates.

02 Where more than one process matters

Some situations need more than one transfer named:

• A wood or coal fire — radiation to the room, convection of hot gases, conduction into the grate.
• A car radiator — conduction through the metal, convection of water (and of air over the fins), plus radiation from the hot surface.

Name the processes that are significant, not every process that exists in physics.
