A) solid phase
B) liquid phase
C) solid, liquid and gas phases
D) no phases are present at this point

Answer 1

The answer is C) solid, liquid and gas phases

Step-by-step explanation:

This point is called the triple point bc solid, liquid, and gas phases can exist together.

hope this helps :)

Answer 2

The correct answer is A. The water at this conditions is in the solid phase. This can be verified by using a phase diagram. A phase diagram is a figure which shows the phases of a certain substance at a specific temperature and pressure.
