### In the lessons

In everyday life radiators heat homes and classrooms in the UK, Ireland and other cold places; people dry gloves on them and children are warned they can be hot. In science radiators show heat transfer: they warm the air by convection and radiation. Phrases: «turn up the radiator», «bleed the radiator», «car radiator».

### Note

Countable: «a radiator». From «radiate» (to send out heat or light). Despite the name, most of a home radiator's heat moves by convection, not radiation. In American English a «heater» is often used for room heaters.
