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.

What is the temperature in 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.
How do insulated containers maintain the temperature of the contents?
The inner part of a thermos flask is a seamless container - usually made of glass. It is blown into a mould while the glass is molten - and formed so that there is a thin layer of space between the inside and outside walls. The air between the two layers is sucked out - creating a vacuum. Since heat cannot travel well through a vacuum, the liquid inside the flask stays hot (or cold) for a long time.
The inside surface of the glass inside a vacuum bottle is coated with aluminum to prevent heat loss by?
By radiation
Why do the particles move faster in a vacuum?
Particles do not move faster in a vacuum. Particles move faster when the temperature increases.
Is there air molecules inside a vacuum?
Yes, it is true. Hoped that helped.
What is room temperature and pressure?
NIL... Does NOT exist...As there is no medium inside the vacuum.

Is there inert gas inside a thermometer?
No. The tube inside a thermometer is vacuum. If there was a gas inside, the pressure changes due to temperature changes would cause the liquid inside to expand/contract unevenly.
Does water inside a vacuum boil at a higher or lower temperature than it does under normal pressures?
It boils at a lower temperature because of the less energy needed.
How does a vacuum flask reduce heat loss from a hot liquid inside?
Due to open space isolating the flask from external temperature
Energy cannot be transferrd in vacuum what is the temperature of vacuum?
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.
In a vacuum there's no what?
A vacuum is an empty space with nothing inside it.
How could you demonstrate boiling point?
A light layer of vacuum grease is applied to the rim of the belljar. Water at room temperature is placed inside and the vacuum pump is then used to evacuate the vessel. When the air pressure is reduced to the vapour pressure of water at room temperature the water will begin to boil.
Can you assign temperature to a vacuum?
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.
What goes on inside a vacuum?
by definition a vacuum is empty. as in nothing. there is nothing in a vacuum. so the answer is, by current knowledge, that nothing happens in a vacuum
What causes your lungs to pull in air from the atmosphere?
By expanding them, you create a vacuum inside them; given a portal (your mouth, nose), the vacuum will pull the ambient air in, just as a vacuum cleaner pulls things inside by creating a vacuum.
Why is the temperature of vacuum negligible?
because there is no air
