Answer 1

Concepts and reason

The concept of the phase diagram is used in this problem. The phase diagram is used to understand conditions at which phases occur and coexist at equilibrium. It is a graphical representation of physical states (such as solid, liquid, and gas) of a substance under different conditions (temperature, pressure, volume).

Find the appropriate word for the transition shown by the indicated lines and points in the given phase diagram on the basis of their conditions.

Fundamentals

Phase diagram of the water system is given as shown below.

The phase transformation can be represented as shown below.

(1)

The given phase diagram is shown below.

Line from D to C indicates that the gaseous phase converts into the liquid phase. Thus, the transition shown by the line from D to C is condensation.

(2)

The given phase diagram is shown below.

Line from C to E indicates that the phase transformation from liquid to solid which means freezing. Thus, the transition shown by the line from C to E is freezing.

(3)

The given phase diagram is shown below.

Line from C to D indicates that the phase transformation from liquid to gas which means boiling or vaporization. Thus, the transition shown by the line from C to D is boiling.

(4)

The given phase diagram is shown below.

Line from E to C indicates that the phase transformation from solid to liquid which means melting. Thus, the transition shown by the line from E to C is melting.

(5)

The given phase diagram is shown below.

As per the above phase diagram, at point A all three phases (solid, liquid and gas) of a substance coexist in equilibrium. Thus, the point indicated by A is the triple point

(6)

The given phase diagram is shown below.

Line from F to E indicates that the phase transformation from gas to solid which means deposition. Thus, the transition shown by the line from F to E is melting.

(7)

The given phase diagram is shown below.

In the given phase diagram, at point B liquid and gas phase have the same density therefore, these are identical. Thus, the point indicated by B is the critical point.

(8)

The given phase diagram is shown below.

Line from E to F indicates that the phase transformation from solid to gas which means sublimation. Thus, the transition shown by the line from E to F is sublimation.

Ans: Part 1

The transition shown by the line from D to C is condensation.

Part 2

The transition shown by the line from C to E is freezing.

Part 3

The transition shown by the line from C to D is boiling.

Part 4

The transition shown by the line from E to C is melting.

Part 5

In the given phase diagram the point indicated by A is the triple point.

Part 6

The transition shown by the line from F to E is deposition.

Part 7

In the given phase diagram the point indicated by B is the critical point.

Part 8

The transition shown by the line from E to F is sublimation.
