Do any substances (except water) exist in more than one form (solid, liquid, gas) at particular temperature and pressure?
How do scientists determine the different forms that a substance can exist in?
Scientists typically use a combination of experimental measurements and computational modeling to determine the different forms that a substance can exist in. They study the behavior of the substance as it is heated or cooled, and they use their observations to develop a phase diagram that shows the different phases that the substance can exist in at different temperatures and pressures.
