There a 3 light bulbs in a room that has no windows. You can only see in the room when u have entered it as the door is closed. there are 3 light switches outside the room.When u enter the room you are allowed to have 1 light bulb switched on.you are only allowed to enter the room once before coming back out and then knowing which light switch turns on which blub. How is this done.

easy.
Turn on the first switch, leave it for ten minutes to get hot.
Turn it off, and turn on the second switch.
rush into the room, see which one is hot and thats the first switch.
The cold (turned off bulb) is obviously the switch you havent touched

And that would help you find out which switch controls which lightbulb how?
