Here's why:
* Large Surface Area: Radiators are designed with fins or other features that increase their surface area. This allows for greater heat transfer.
* Conduction: Hot water or steam flows through the radiator, heating the metal. The metal then transfers heat to the surrounding air through conduction.
Other examples of devices that use conduction to heat air include:
* Baseboard heaters: These heaters have a long, flat surface that sits against the wall.
* Space heaters: Some space heaters have metal fins that increase their surface area.
* Heating elements in ovens and stoves: These elements heat up and transfer heat to the surrounding air by conduction.
