How does a vacuum affect the temperatures of surrounding objects?

If a vacuum is created in a lab, does its temperature tend to 0K? Does this mean that its container would be very cold to the touch? If, say, water was poured into it, would it freeze instantly?

A vacuum doesn't affect temperature, as such. If there were a compete vacuum, there would be nothing in it to contain energy. Therefore, no energy cannot manifest itself as any heat.

A vacumm will, however, affect the TRANSFER of heat. If there is no mass (i.e. there is a vacuum between two systems) then two of the three forms of heat transfer cannot take place - conduction cannot take place as there is no continuous medium. Like wise with convection.

Radiation can still take place.

If you were to put a conventional (air cooled by means of radiator/heat sink) PC in a vacuum, it would overheat. There is nothing to transfer the heat into, so the unit, itself will continue to heat up, with only a tiny amount of radiative heat dissipation (insufficient to cool it).
