The surface area of an unclothed person is 1.5m ^2 and thier skin tempature is 33 degree celcius. This ideal person is located in a room with a tempature of 65 dregrees F. and has an emissivity of e=0.95 suppose the room has dimensions 4mx9mx18m a) suppose you and your closest 10 friends come into this room and heat it up. suppose your clothes are in equilibium with your skin and have the same tempature and emissivity. Further suppose that your net power into the room remains constant . How long does it take before the room to get to hot say 95 degrees
