Superfluid is a magical state of matter.
Under normal circumstances, liquid nitrogen at minus 270.38 degrees Celsius becomes an ideal fluid with peculiar properties, namely superfluid, when its internal friction coefficient becomes zero.
This means the fluid has no internal viscosity at all.
There are several important characteristics of superfluids.
Such as complete lack of viscosity, zero entropy, and infinite thermal conductivity.
In short, it can flow endlessly without losing energy.
At the same time, there is no adhesive force between superfluid molecules, so the molecules can move independently.
It can pass through pores with a diameter of 100 nanometers.
Lu Li keenly noticed that the superfluid state he transformed into was even more "magical" than the superfluid in physics.
Not to mention a pore of 100 nanometers in diameter.
Even if there was only a quark particle ahead, he could pass through it.
As if able to permeate anything.
