Why isn’t the temperature of a vacuum absolute zero if there is nothing to store the heat energy?
It would be if it was absolute vacuum (0 kpa). But we cannot get true 0 pressure even in laboratory conditions. Just like temperature we just try our best to get very close.
The Short Answer
It would be if it was absolute vacuum (0 kpa). But we cannot get true 0 pressure even in laboratory conditions. Just like temperature we just try our best to get very close.
