Question

Match List I with List II:

LIST I	LIST II
A. Subcooled water	I. 1 bar and 134°C
B. Superheated steam	II. Dryness fraction = 1 and 100°C
C. Steam at critical state	III. 20°C and 1.01325 bar
D. Saturated steam	IV. 374.15°C and 220.8 bar

Choose the correct answer from the options given below:

• A. (A)-(I), (B)-(II), (C)-(III),(D)-(IV)
• B. (A)-(II), (B)-(III),(C)-(I),(D)-(IV)
• C. (A)-(III), (B)-(II),(C)-(IV),(D)-(I)
• D. (A)-(III), (B)-(I), (C)-(IV),(D)-(II)

Hint:

When working with thermodynamic properties of water remember that Subcooled water exists below its saturation point typically at lower pressure and temperature Superheated steam is above the saturation temperature Critical state is where both temperature and pressure reach critical points Saturated steam is at the boiling point with a dryness fraction of 1

Answer 1

The Correct Option is D

Below are the characteristics and corresponding properties for various water states:

• Subcooled water: Water at a temperature below saturation, correlating with (III) 20°C and 1.01325 bar.
• Superheated steam: Features high temperature and low pressure, corresponding to (I) 1 bar and 134°C.
• Steam at the critical state: Characterized by critical pressure and temperature values, corresponding to (IV) 374.15°C and 220.8 bar.
• Saturated steam: At boiling point with a dryness fraction of 1, matching (II) dryness fraction = 1 and 100°C.
