The heat is transferred from the burner to the pan to the cheese burger to my hand all because the hot heat particles vibrate and move up while the cold particles go down.
I'm going on a hot air balloon trip.This hot air balloon works because of convection. Convection is only through liqud and gas like air. The heat of the fire heats up the air in the balloon and heat rises and cold sinks.
I'm stranded in the freezing cold arctic, soooo I made a fire. The heat from the fire is transferring into my body through as the cold air leave me.
