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.
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.
Technically no. Temperature is effectively the average speed of the particles. If you don't have any particles then you have no temperature. Although an Infra-red detector would work, and Infra-red radiation causes heating, that would not be the temperature. Also, this is all theoretical anyway since total vacuums do not exist.
The temperature sensitive resistor commonly used on vacuum gauges is called a thermistor. It is a type of resistor whose resistance changes significantly with temperature, making it useful for measuring variations in temperature within a system.
The most likely velocity of a molecule in a vacuum is determined by its temperature and follows a Maxwell-Boltzmann distribution, with a range of velocities. The average velocity of a molecule in a vacuum can be calculated using the root-mean-square speed formula, which is proportional to the square root of the temperature in Kelvin.
The vacuum between the glass walls in a vacuum flask acts as an insulator, preventing heat transfer through conduction or convection. This helps to maintain the temperature of the contents by minimizing heat loss or gain.

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.
because there is no air
Both time and temperature can decrease the vacuum draw of an evacuated tube. Hence the provided expiration dates and storage temperature of tubes. The vacuum of a tube will decrease if it is too old or if stored at a colder temperature than recommended.
Quality vacuum gage is required ;-) engine at running temperature around 18 to 20 inches Hg = vacuum
Temperature is the vibration of particles.In a true vacuum there are no particles.Therefore, a true vacuum cannot have a temperature other than 0K (approx-273C) i.e. absolute zero
When engine temperature rises, the brake sees vacuum and pulls the choke open.
because they decompose at higher temperature.. under vacuum they can be boiled at lower temperature than their boiling point
The proper way to take the temperature of vacuum packed foods is with a metal stem thermometer. To take the correct temperature, put the thermometer in the center of the food.
It shouldn't be left at room temperature. The vacuum packaging sets up a perfect environment for Clostridium botulinum.
