What is a key characteristic of superfluid helium-3?
Opacity
Viscosity
Zero viscosity
High density
Answer
Zero viscosity is a key characteristic of superfluid helium-3. This means that it can flow without any resistance, making it an ideal fluid for studying quantum mechanics. Superfluid helium-3 is also very cold, with a temperature of only a few millikelvins. This makes it a very fragile substance, and it must be handled with great care.
