Crispy cooked bacon is supposedly safe at room temperature because the water activity is too low for pathogens to grow. See Related Links.
Cooked bacon is a protein and may be safe for an hour or so at room temp, but after that it should be kept at either less than 40°F or higher than 140°F.
No, not in its uncooked state. You can, however, cook it and then freeze it.
In a vacuum temperature is inapplicable. Temperature is a measure of the kinetic energy of the molecules that fill a defined space. In a vacuum there are no molecules so --- no temperature.
Depends on the external temprature, it should be treated the same as an uncooked bacon, the fact that it is vacuum sealed does not mean it will last longer
The process of soft canning is more of a combination of canning and vacuum sealing. The food is preserved in a package that may be left at room temperature until it has been opened. Once you have opened the package, the food must be refrigerated or frozen to avoid bacterial growth.

Vacuum packed vegetables are blanched, which is a process of partially cooking them in boiling water. They do this because raw vegetables give off gases when stored. Vacuum packed fruits are uncooked when frozen.

A perfect (completely empty) vacuum would have no temperature, since temperature implies movement of particles. However, any real vacuum has some particles (the density is simply less than normal air pressure, for instance); the temperature in this case can vary, just as the temperature of air, or the temperature of water, can vary.
Answer Yes, you can. I think the answer is no. A physical object in a vacuum can have some energy/heat in it, and the energy associated with electromagnetic radiation can have energy/heat associated with it, but the vacuum itself cannot. ______________________________________________________________________ There is no such thing as a vacuum.
In an absolutely perfect vacuum, there is no defined temperature at all. The temperature simply doesn't mean anything. Of course, there isn't really anything that is a perfect vacuum.At very high vacuum, at equilibrium, the temperature will be determined by whatever the container holding the vacuum is in thermal contact with. Something inside an imperfect vacuum isn't at any particular temperature -- if it is at equilibrium, it will be at whatever temperature the things around it are at. However, the rate at which is reaches equilibrium with may be very slow because of the vacuum. If it not at equilibrium, then the object in the vacuum will be at whatever temperature it was set at until it reaches equilibrium with the things around it.
because there is no air
