# so if it doesn't change, it stays at the same temperature it was at when the vacuum was created?
it still 'has temperature'?

I agree that it wouldn't have any 'heat energy', but it would still 'have temperature'.

I'm in a finger-quotes mood right now.

# *thinks*
I think the act of creating the ideal vacuum with lead to something having 0 (absolute) temperature

hangon! all of this can't happen in the first place. If there is no temperature, by definition, then at absolute zero and that violates one of the laws of thermodynamics.

# THANKYOU
I was going more for the definition of measurement rather than the whole thermodynamics thing, but we both got to the same place in the end.

Of course, we could start talking about entropy but that would just start a whole other shitstorm.

# Wait, entropy would stop a shitstorm, not start it
I still think I'm doing pretty well considering I've been drinking for seven hours now.

# Naa
The temperature on the thermometer wouldn't change because the amount of heat energy held by the thermometer itself would remain the same, since the vacuum around it would stop any heat energy from being lost or gained.

# You're forgetting that this is a magical thermometer that doesn't occupy any matter
It wouldn't have any heat energy.

# If the thermometer is hotter than the surroundings
then it would slowly cool down. If it was colder, then it would slowly heat up.

Think of a vacuum flask - sure, it keeps hot things hot and cold things cold, but not for ever! Damn you and your hollow promises of eternal piping hotness, vacuum flasks!

# NO NO NO
The thermometer doesn't occupy any matter. It behaves exactly like its surroundings. This is crucual to my point.

I can't remember why but it is.

# If the thermometer doesn't occupy any matter
how can it give a temperature reading? I is confuzzled.
