Dunno how I want to say this... there can be energy, realily converted into heat. (like radiation, light, etc)
 
But in a pure vaccum, it should be 0deg K. But how are you going to measure that... in the massive size of our universe, it's concieveable that a pure vacuum has yes to exist.

A pure vacuum cannot exist in reality.
 
As far as the original question goes. Since temperature is a property of matter (no one cares what you think bomber), there is no temperature. So the answer IMO, is no.

"heat" is transmitted or present via 2 means, convection (where the matter is heated and transfers heat to other matter it contacts), and thermal radiation (where the heat is transfered in infrared light, which can pass through a vacuum). Basically, a true vacuum can't contain heat, but heat can be transmitted through a vacuum.

I personally would go with no for the same reason as what Rudster said

Idk my mind is so freaking screwed up atm I am gonging through so many possibilities.

anwser it like this
 
yes/no the end

But if there is no molecules then there is no movement.
No movement = no kinetic energy
No kinetic energy = 0 k

One doesn't determine the temperature of a vacuum. Just as 'nothingness' has no color, taste, smell, etc. it also has no temperature. That is because there are no particles whose kinetic energy can be measured or averaged.

Only objects within a vacuum can have a temperature, and that temperature will depend on the balance of incoming and outgoing radiation. Electromagnetic radiation can travel through a vacuum, so objects in space of any temperature above the near absolute zero (0 Kelvin = about -273 deg C.) temperature of cosmic background radiation (which is about 3 Kelvin) will radiate energy into space. Without another source of energy replacing that loss (a nearby Sun, for example) the object's temperature will decrease. That is why you read about 'the coldness of outer space'.

 
I win.

nothing in this universe is absolute zero.
 
I explained the physics correctly.
 
@Falcon; the worry about thermo differential in space is not due to imperfect vacuum, but rather the heat an object feels from radiation (mainly from the sun). The dark side of a satellite is extremely cold and the lighted side extremely hot and not because of the temperature of the matter around the satellite. 
 
I'm not debating this, I'm telling you guys the way it is. We are talking about my profession here.

Yes there is temperature in a vacuum. but just be sure to explain whichever reasoning you have well. for teachers in physics and applied sciences, theyll take almost any answer thats well thought out. 

Idk I am gonna start a debate tomorrow.

I think there is heat in vacuum. Though, apparatus used in the biological field that needs to isolate heat are done with vacuum, because heat cannot be transfered through a vacuum.
So i don't effen know.

vacuum DOES have temperature, why do you think NASA has to worry about insulation and heating/cooling issues. 2 ( i believe) of the panels on the ISS are actually heat exchangers 

 
Correct answer first thing that came to mind is that in space if your space suit tears not only will you run out of air but you will probley freeze to death hence the concept that space is in fact a cold environment. And a vacume is not nothing it is something your just not in an atmosphere, I think it is a question of density in a specific area you nominate in space and what gasses are present in that area. Space after all does contain gas clouds radiation ice is it even possible to find a portion of space that is devoid of any of these elements.
 
I get the point others have made that in order to define temperature you need to have atoms moving to create heat they would define a vacume as having no particles therefore no heat. In reality though if you introduce an object into the vacume it will experience what our sences would define as a temperature and with out some source of radiation or heat or insulation we would freeze to death.
 
 

Is there a source of heat in an absolute vacuum?
 
Yes, there can be.  Radiation can pass through a vacuum and therfore there is a source.
 
But that wasn't the question.
 
"Is there temperature in a vacuum?"
 
Absolutely not!  Temperature is a measurement of heat.  Measuring heat requires that you measure the movement of mass.  A vacuum has no mass and therefore you can't measure movement.  Heat can pass through the vacuum but won't create any temperature.  Only when mass is inserted into the vacuum will temperature exist (and then it will no longer be a vacuum).

One thing that you have to realize is this, in a physics class, reality and the questions that they ask are two very different things.
 
Often you will get questions in physics that asky you to ignore non removable variables. Thus the reason why you are having an issue dealing with this question.
 
By theory, the answer is NO, but the likely hood that you would ever
A have a prefect vacuum
and
B devise a way to measure temperature without interfering with that perfect vaccume
 
Is as closer to border line impossible as you can get.
 
But for the purpose of the question, the answer is NO
