I think ionic but I can't just guess it's for a quiz...

Why do you think the wire glows?
anonymous

Uhg, physical change then maybe? I dunno. \(._.)/

i would say, this is an example of resistance, which provides light and heat. which means it's a ------- change ?

Chemical!

Or no? >.<
Koikkara
  • Koikkara

Because it provided light and heat?

Hmm..The metal wire in an incandescent lightbulb glows when the light is switched on and stops glowing when it is switched off. This simple process which takes placethrough chemical reactions in a process called bioluminescence

And so i suggest chemical change... not physical as no change in bulbs coil takes place,and not ionic as ionic changes produce no light.

@Cuanchi \(Good~Question~!\) Well, does burning of film, when a bulb glows shows any physical change to its surrounding glass or the film ? film glows bcuz of heat but doesn't change the film or its shape. but when you refer luminescence you find the real change.
