Respuesta :

yes you are right .. X is undergoing a change from solid to gas at point E

Yes you are right as from the phase diagram it can be seen :

A. Substance X is in the solid phase in the area shown by “1”.


B. Substance X exists as a solid, a liquid and a gas at point D.

D. Substance X is a liquid in the area shown by "2"
