Question

According the phase diagram for H₂0, what happens to the phaseswater at 0.5 atm pressure as the temperature is decreased from 110°C to -10°C?Pressure (atm)1-0.5-0.25--10Ice(solid)0.01Water(liquid)Water vapor(gas)100Temperature (°C)

Answer 1

A. Water changes from a gas to a liquid to a solid.

Step-by-step explanation:

We can see the following points in the diagram:

- Point A: water starts at 0.5 atm and 100°C, so it is vapor (gas).

- Point B: water changes from vapor to liquid.

- Point C: water changes from liquid to solid.

- Point D: water as a solid reaches a temperature of -10°C.

So, water changes from a gas to a liquid to a solid.
