There is a room. It is completely sealed. There is a door leading into the room. You can only open the door ONE TIME. The door closes and locks after you leave the room. There are three light switches. One of them turns on a lightbulb the room. The other two lead to nothing. You can only have one switch on at a time. How do you find out which light switch turns on the one in the room?

You cannot do anything other than flipping switches (one at a time), opening the door,and touching without moving.

OKAY. I REPEAT!
THE ROOM IS COMPLETELY SEALED.
YOU CANNOT SEE INTO IT!
ONE SWITCH AT A TIME!

Turn on one light switch, leave it on for awhile. Turn off the first light switch,and turn on the second. Go into the room. If the light is on, you know it was the second, if the light is off and the bulb is warm, it was the first switch, if the light is off and the bulb is cold, it's the light switch you didn't try.

"The door closes and locks when i LEAVE the room" necessarily implies i am IN the room. I simply try the switches, one at a time until i find the one that turns on the light.

You turn on one switch, if thaht isn't it then turn it off and try another one untill you find the one that turns on the light switch. Two light switches will never be on at the same time. How was that hard, unless I didn't read the question right?

Try one switch at a time until you find the right one. Don't leave any of the others in the on position while trying another. ONE AT A TIME!

Turn switch "A" on. Wait 5 minutes
Turn switch "A" off
Turn switch "B" on and enter the room.
If the light is on, then the answer is switch "B".
If the light is off, but warm, the answer is switch "A".
If the light is off and cold, the answer is switch "C".

You open the door to leave the room, then try the switches. At that point, who cares, you're no longer in the room ~

turn one on before you go into the room. if it's dark in the room, it's one of the other two. you have a 50/50 percent chance of getting it right. you may, then again, you may not. but, you have a better chance now at getting it right.

have something keeping the door open so you can go in and out whenever you want and turn on every switch to see which one turns on.

You don't know because the door is shut and won't open. It was already opened that one time. So there's no need to use the switches because it doesn't matter.

you turn on two light switches, and wait a while. then turn one off. then you go in the room. if the light is on, its the ligt you left on, if its hot but turned off, iuts the switch you turned off then on, and if its off and not hot, its the switch you never touched.
im good.
