It is the lowest possible temperature.
Q5.4
As atoms and molecules warm, the vibrate more vigorously with more average
random translational kinetic energy. As they warm the pass typically through
four stages:
- While cool, they have a fixed arrangement with respect to each other and
they are very close together, with a spacing of about 1 nm. They form a solid.
- As they warm, the arrangement breaks down, though the spacing stays close
to 1 nm. This is a liquid.
- As they warm, the molecules separate from each other, forming a gas.
- Warming more still breaks down the molecules into atoms and atoms into
electrons and ions.
