Answer:

No, but its behaviour approximates that of an Ideal Gas.

Explanation:

At normal temperatures and pressures, helium behaves ideally. However, if the gas is compressed and cooled repeatedly, the gas will liquefy. As a cryogenic liquid with an extremely low boiling point, approx. #4# #K#, liquid helium is used to achieve superconductivity; e.g in modern NMR spectrometers.
