The behavior of this liquid phase is normal and identical to any other liquid … WebCan helium be a solid? Helium is the only substance that can maintain its liquid state at near absolute zero and has no triple point. Solid helium can be obtained only under high-pressure conditions (at T<1.0 K, the pressure must be higher than 2500 kPa to obtain solid HeII or higher than 3000 kPa for HeI).
