Question

How can pure noble gases become solids at low temperature? what interaction do they have?

In: Chemistry

Answer 1

Whether a substance is a solid, liquid, or gas, simply depends on its pressure and temperature. So any substance can be in any of those states if the pressure and temperature are right.

For noble gases, like any other gas, this requires lowering the temperature and/or increasing the pressure.

Also, Helium *can* exist as a solid:
