This is a very strange question, air temperature ranges from well below -500 degrees C, all the way up to, well it's hard to test these exactly. The point being, if the sun goes out, we'll freeze, if the atmosphere is gone, either we'll be super hot, or just vaporized. There is no way to actually test it though. You may want to reword your question.
The range of air temperature depends on the location and period among other factors. For instance, San Francisco experiences 49.3F in January, while Dodge City experiences about 31.3 F during the same period.
