Elements in different states

Postby Shuyi Yu 1B » Thu Jan 24, 2019 1:17 pm

Can all elements be converted into solid, liquid, or gas states given that the right amount of energy and pressure is applied?

To my understanding, all matter can move from one state to another and the physical state changes can be largely dependent by its temperature and pressure. These phase changes occur when certain points are reached such as the element's freezing or melting point. To my understanding, helium, a noble gas located in Group 18,is special because its boiling and freezing points are lower compared to other elements and thus it is not enough for it to solidify through sufficient cooling at normal atmospheric pressure and hence a pressure of 25 atmospheres at a temperature of 1K is needed to change into a solid state.

Not really. I think we only are supposed to know the standard state.
