OK guys (gals?),

Please feel free to laugh at me for this one, it is late, my brain is mush and I can't find my trusted rule of thumb book...


What will the temperature rise be in 1m2 of air if 1 watt of heat is added to it for 1 hour?
(Assuming no losses or other heat transfers occur and that we start with dry air at 20ºC)


I will now go and collect my free bus pass, get my slippers on and complain about the youth of today.
