How hot is the air in a hot air balloon?

Answer:
The internal temperature will depend on various factors such as the load on the balloon, it's size, and the ambient air temperature. The loading of the balloon will generally be arranged such that the the internal temperature will be around 100C or 212F. If the temperature is taken much higher than this, to say 120C or 250F the fabric will start to degrade.
