Thermochemistry questions

At atmospheric pressure, helium can exist in all three phases, as well as a supercritical fluid phase near absolute zero.

Solid and gaseous helium never exist in equilibrium with each other at any temperature or pressure.

Helium does not exist as a solid below $25$25 atmospheres due to its low mass.

At room temperature, helium exists as a gas, and as pressure increases eventually becomes a solid.
