MOVIE!!! Lets look at the heat transfers in a theater!!

In this theater the lights radiate heat.
Not only is radiation happening, but convection is occurring to from the heaters.
Eating popcorn? Well believe it or not, but smelling the popcorn is convecting heat. Also the popcorn machine conducts heat from the pan to the corn kettles.
The hot dog machine also conducts heat by transferring heat from the rollers to the hot dog.
